Transfer in Ballroom Dance:

Transfers of Dance-Patterns

for creative leading, with more
variety-and-fun for your partner!

by Craig Rusbult, PhD (in Education, C&I)

I'm writing this page to help you decrease boredom by increasing variety. 
        the problem:  Based on my experience when playing the role of “leader” in ballroom dancing,* I think most leaders (aka leads) feel uncomfortable when, after a minute of a 4-minute song, they have led all the patterns they know so they must begin repeating.  A leader doesn't want to make the dance boring for their partner.  They want to make dancing more fun, and the adventure of variety can help this happen!   🙂        {* A feeling of discomfort — because I want to be more effective in helping each dance be a fun adventure for my partner — was stronger in my early days as a leader, but even now it hasn't disappeared. }
          a solution:  To increase the variety-and-fun for their partner, a leader can multiply the number of patterns that are available if they use transfers-of-patterns, IF when they learn a pattern in one kind of dance, they transfer this pattern to other dances.  For example, most patterns from one 6-step dance (waltz, foxtrot, rumba, mambo, cha cha,...) can work well in other 6-step dances.  And we can transfer patterns from one 4-step dance (foxtrot, swing,...) to another.  Using transfer-of-patterns is one strategy (among many) for increasing fun with dancing.     transfers in 6-Step & 4-Step Dances }

        a problem (for both dancers):  Along with my partner, I also was bored when I knew only a few patterns, so I had to repeat these patterns (over & over & over & over) during an evening.  Now I know many more patterns — although not nearly what is possible, what I've seen other dancers do, or I can imagine — but boredom still is a problem for a leader, because...  Followers get to dance whatever is led by a variety of leaders, so they can have many “magical mystery tour” experiences, often wondering “what will happen next?” throughout the evening, and getting different answers from each new partner.  But as a leader, I get to dance only what I know (nothing more), over and over.
        variety with quality:  Therefore, to increase fun and decrease boredom, for my partner and myself, I enjoy learning new patterns that work smoothly.  A pattern will "work smoothly" when it's compatible with the physics-and-physiology of myself and (especially) my partner, when the physics allows a smooth transition from the direction she was moving to the new direction she will be moving after the change I ask her to make, and when she can make this change because it doesn't demand more of her physiology than she is capable of doing, and will enjoy doing, with her body (structural frame, muscles of legs & feet,...) and mind (in responding appropriately to my leads).    {note: I will refer to leaders & followers as he & she, because that's been my experience, and it's usually (but not always) the gender-roles, and it's traditional, is linguistically easier, etc.}   And also psychology because a leader must communicate clearly – with good timing (not too early, not too late) – what is planned for “our next actions” so the follower can “do these actions” to produce effective cooperation for the partners.
        These principles for skillful dancing (by using physics-and-physiology and psychology) are explained with more detail in more about leading & following.
 


 
Using Transfer-of-Learning to Increase Variety
        Teaching for Transfer:  In 1994, I wrote a series of pages that outline a system I developed for helping students quickly learn a wide variety of ballroom dancing patterns, with each having rhythm, timings, and movements that “work” so the pattern feels good and looks good.  The basic strategy is teaching for transfer so when students learn a pattern in one kind of dance, they can transfer this pattern to other dances.
        Two Kinds of Dances:  This system is based on my observation, in 1992-1994 when I was learning how to dance, that most ballroom dances are in two categories (six-step or four-step) and dances within each category can share many of the same step-sequences. 
        Transfers of Patterns:  For example, many patterns from any six-step dance (waltz, rumba, foxtrot, cha cha, mambo, salsa, nightclub two-step,...) can be used in other six-step dances, so there can be major transfers of learning.  Similarly, in four-step dances (foxtrot, east coast swing, country two-step,...) patterns can be moved from one dance to another.  And sometimes patterns can be used in both 6-step and 4-step dances, as in hybrid mixes (see end of page) and adaptations.
        non-Transfers:  But sometimes a pattern cannot be easily transfered between dances, due to differences in tempo (if during one dance it's too fast for comfort, or too slow) or in the styling of a dance.
        Rhythms:  For both groups, 6-step and 4-step, several rhythms are used.  A 6-step pattern can be danced in 6 counts (1 1 1 1 1 1) as in a waltz, or 8 counts (2 1 1 2 1 1, or 1 1 2 1 1 2) in foxtrot, rumba, mambo, or nightclub two-step,* or the 8 counts (1 1 triple-step 1 1 triplestep) of cha cha.  And a 4-step pattern can be modified from “slow, slow, quick quick” in 6 counts (2 2 1 1) to “trip-le step, trip-le step, quick quick” (also basically 2 2 1 1) or “quick quick quick quick” in 4 counts (1 1 1 1).    {more about Rhythms & Tempos and Measuring & Changing Tempos}

        Also, Transition Diagrams (at end of page) illustrate the principle of a leader knowing the options for “what can be done next,” and making skillful real-time decisions about changing to “the next pattern.”  This knowledge/skill is essential for making decisions that allow a smooth flow-of-motion from one pattern to another, by cooperating with our physics-physiology-psychology.
 
        * a problem:  In a complicating factor, some 6-step dances with 4-count music are taught by different teachers using different rhythm-patterns.  For example, rumba is commonly taught in two ways, with some teachers choosing “Slow Quick Quick” (S-QQ which is 211) but others “Quick Quick Slow” (QQS- which is 112).  Some dances always use one or the other, as with S-QQ/211 (foxtrot) or QQS-/112 (mambo, cha cha) while other dances (rumba, nightclub 2-step) are taught both ways by different teachers.  This can make a transfer more difficult, because (for example) if a particular pattern begins on the initial Slow (S) the leader must begin this sequence on the 1-step (of the 6-step pattern) and the musical 1-count with S-QQ;  but with QQS- it's on the 3-step (of the pattern) and 3-count (of the music).  This requires changing habits, and it makes transfer more difficult.
        two solutions:  So should a leader change all of their rhythm-thinking to either S-QQ or QQS- , to make things less difficult?  Maybe.  But probably you should try to become comfortable-and-skillful with both, although dancing more with the rhythm you prefer, so you can become more skillful due to the extra practice.   /   If you want to transfer patterns from a QQS- dance (mambo, cha cha, nightclub two-step), you can count your rumba as QQS-, and this “matching of rhythms” will make the timing of step-transfers easier & better.  But for a transfer of patterns from a foxtrot (or waltz, IMO) that's S-QQ, you can “match rhythms” by dancing your rumba as S-QQ.  Personally, I like S-QQ for Rumba (because it feels more like a smooth waltz), but I also can “think Nightclub Two-Step” and feel comfortable with QQS-.
     

        Variety in Leading:  When dance-leaders know how to transfer patterns from one dance to another, this greatly increases the variety of the patterns they are able to lead.  Learning the principles of pattern-transfer also will help followers, but it's especially useful for leaders.  Knowing a variety of patterns lets a leader use the principle of mixing confirmations with surprises that is useful in dancing & music, humor & drama, in conversations and other areas of life.  But although variety is a nice “bonus” it's more important to dance each pattern with high quality — so it feels good (for both of you) and looks good (for whoever is watching)* — by cooperating with your partner to make it work well.
        Variety in Styling:  Of course, the same pattern can (and should) have different styling when the dance-context changes, due to differences in music, tempo, rhythm, mood/attitude, skill of partner, and relationship with partner.  In some ways this is analogous to variations in musical styles — as illustrated in a book I bought that included a phonograph record with the same tune played in many styles (swing jazz, be bop, blues, march, classical, dixieland, rock,...)* — and similar variations occur when the same dance pattern is used with different stylings in different dance-contexts.
        * Two responsibilities of a leader are:  don't injure your partner, and help them look good.   Of course, how you do these will depend on your partner.  Some of my partners seemed able to cope with anything I could do (within reason), no matter how complex or fast, but others have been less nimble and skillful.  So I adjust.  At two extremes...  elderly ladies at a community center, who were less nimble-strong-skillful, more vulnerable to injury, so our patterns were easier & slower, by contrast with...  a medium-young lady at a church dance, held in the Monona Center with a hardwood dance floor plus a larger area with low-pile carpet that was smooth but with high friction, that wasn't ideal for a follower who must make fast movements that are unplanned.  After the dance I noticed she was wearing high heels;  I said “if I was wearing those heels, within a few seconds I would have been on the ground with sprained ankles” and she said “with enough practice we can become very skillful at doing difficult things in heels.”
        * Although using “variations on a theme” is useful for teaching, in dancing or music, the usual reason for musicians to adjust style is when they want to express themselves artistically.  Musicians like to play their own version(s) of a song.  For example, I've heard many versions of Summertime played in a wide variety of styles by many bands (i.e. teams of musicians) and each team performed it with excellent quality to make wonderful music, in very different ways.

        Adding Variety with Hybrids
        Pure (6-with-6 or 4-with-4) Hybrids:  Because "many patterns from any six-step dance (waltz, rumba, boxtrot, mambo, cha cha,...) can be used in other six-step dances," during one type of dance (waltz,...) you can use a pattern that is unusual for this dance but is common in another six-step dance — IF it can be suitably adapted so it feels good and looks good — for variety and a change of pace that mixes confirmations with surprises.  In a similar way, dancers in Country Two-Step often mix patterns from two 4-step dances, foxtrot and swing, and the resulting hybrid is what you typically see on a dance floor;  they also can use patterns from 6-step dances, if these are adapted to make them fit smoothly into the 4-step dance rhythms.
        A Hybrid Rhythm:  During a 6-step foxtrot pattern in 8 counts ( with patterns of 1_34,5_78) a leader can temporarily shift into the analogous 6-step waltz pattern in 6 counts (with 123,456) for a temporary period lasting 12 counts [or 24, 36, 48, ...] and then shift back into 4-step foxtrot patterns.  When this is done well (and it isn't difficult) the waltz pattern “works” and is a nice change of pace that adds variety.  Yes, throwing 3-count patterns into 4-count music is a bit unusual, but when it's done occasionally it can be a refreshing change of pace, to give your dancing an “extra smooth” feeling for awhile.  This is one way, among many possibilities, to add some variety to the dancing experience of your partner, contributing to the spice of life by "mixing confirmations with surprises."
 

An Important Basic Skill
For both roles, but especially followers, it's extremely useful to practice each rhythm-pattern while moving in every possible direction (forward, backward, sideways, turning left or right) with small steps or larger steps, while keeping the rhythm-pattern of your dancing, and keeping this in time with the music.  You can practice this essential skill on your own, without a partner, just with the music and your own music-coordinated motions.

    And an important skill for leaders is...

deciding “the next pattern” for Improvised Dancing
pattern-options for leading Cha Cha        To make a dance interesting-and-enjoyable for their partner, a leader must know patterns AND make skillful decisions about “what pattern to do next.”  To improve my own improvised leading in 1994, I made “transition diagrams” to show options for “what can be done next,” and I used these diagram-maps (each is like a “roadmap” that shows possibilities) to do mental rehearsing before a dancing event, and occasionally between dances during the event.  For example, this diagram shows, for a Cha Cha, that from the BASIC position there are 8 options (on my diagram, although more than 8 in reality), and after doing a "SIDE" (but not before this) there are 3 new options, shown on the far right.
        improvisation vs choreography:  Sometimes two dancers decide, before a dance, exactly what they will do, by pre-deciding the entire sequence of patterns;  this is very common in competitions, is rare in social dancing.  The two kinds of dancing – improvised and choreographed – are different in some ways, but are similar in many ways.
        iou – Maybe in late 2025, I'll develop other explanations of how to use these diagrams, so other leaders (not just me) can understand them and use them.  And eventually I will make new diagrams, revised to make them better.  Or in a quicker temporary-revision, I'll do cut-and-pastes (from the “mixed” sheets that include waltz, cha cha, rumba,...) to gather all diagrams for each dance together in one place, to make one page for waltz, and another for cha cha, rumba, and so on.

Transition Diagrams show possibilities for “what to do next” in...
waltz    rumba    cha cha    8-count swing    swing    4-count    plus
transitions between dances      mixed sheets (with several dances.

 


Learning from Other Teachers:
        As explained later, I've done a lot of thinking about learning-and-teaching, but not much actual teaching.  Therefore I'm hoping to discuss these ideas with teachers who have more experience.  Although I have abundant experience with teaching in many areas (with wide variety, ranging from juggling to physics)* and with learning in many areas (mental & physical, including ballroom dancing) and with observing teachers (of ballroom, and in other areas), it would be very useful to get feedback from skilled, experienced teachers of ballroom dancing.  This would be greatly appreciated by me, and probably our discussions also would be useful for them.
        If you & I discuss ideas – with a sharing of your ideas & my ideas – you can think-and-say “yes!” or “yes and...” (yes! plus adding your own ideas) or “yes but...” (with questions) or “maybe” or “no because...” (with reasons to disagree).  And so can I.  Each of these responses can be useful when we're learning from each other.
        * My learning-and-teaching experiences with juggling have been especially relevant because some of its teaching strategies would (with some adapting) be useful for helping students learn new dancing patterns.  But useful insights also have come from teaching other mental-and-physical skills (music theory & improvisation and tennis) plus strategies (for learning, and for solving problems), and even from science (physics & chemistry & problem-solving design thinking) & math, and more.


 

Principles for Dancing
        The beginning of this page — to explain why I'm writing it in 2012 — includes basic principles of physics-and-physiology followed by some observations about typical classes and teaching techniques.  Below are additional comments about each of these, plus Movements with Rhythm and Principles for Transfer:

Physics-and-Physiology      
Here are some quotations from the “details” page I wrote in March 1994, with some comments added [inside brackets] in 2012:
Try to develop skill [with frame & leading] early — for the benefit of yourself (so you can learn the principles and patterns) and for your partners (so they will have something worthwhile to “respond to” and can learn to follow skillfully). ...  Let your partner know what you want to happen next, soon enough that she can do it — i.e., soon enough that she is not already physically committed (due to her momentum and direction-of-stepping) to doing what she would need to do if there was a continuation of the previous pattern. ...  Make easily recognizable differences between the leads for one pattern and another.  [This timing-and-clarity of leading will help minimize the “backleading” that occurs when a follower anticipates a lead and begins to do a movement that wasn't led.]*   The “strength” of a lead — whether it physically moves a partner in a certain direction, or merely “suggests” what to do so she can respond (either consciously or in muscle memory) and do it independently — will depend on the pattern, and on the skill and style of yourself and your partner. ... 
    * [Skilled following is not passive, it's a very active process that requires alertly aware observation of cues, combined with quick interpretation of the cues and almost-instant responsiveness, plus coordination and physical agility.  As you can tell, I'm amazed at the skill of good followers, am truly impressed.]  [Backleading should be minimized when it's uninvited, but it can be invited by a leader who wants to learn new patterns from a follower.]
    A good frame defines and maintains a relationship between dancers, so the two of you can “move as a unit” for better technique and for instant communication of easy-to-feel cues for leading-and-following. ... How?  Be solid but relaxed. ... With relaxation, only the muscles that need to be used are being used — no more, no less.  Because muscles are not constantly fighting each other (in an internal tug of war) there is more speed, strength, grace, and endurance.  Also, there is a better message of “body language and mental attitude” communicated to your partner, thus allowing your dancing to be more mutually enjoyable.

{ terms:  My use of he & she, for a leader & follower, is explained earlier. }

        Techniques of Teaching
        I think students learn more quickly when they have take-home reminders of the principles & patterns being taught in a class.  These reminders could be verbal and/or visual:  written explanations of principles, and explanations of patterns plus (when this is useful) diagrams for the patterns.  And compared with 1994, in 2012 (due to the higher quality & lower price of video cameras and editing programs) it's much easier to make instructional videos that offer many benefits, compared with words or static diagrams.
        In classes without these memory-reminders, a limitation on learning is the problem of “mental overload” when learning new movement-patterns during class, if there is too much to mentally remember, so (due to limited class time) the new patterns are not yet solidly known in mental-and-physical memory.  If teachers pace a class very slowly, so students have enough time to thoroughly learn new patterns in their mental memory & physical memory, a learning of new patterns will occur very slowly.  But a combination of in-class practice plus after-class practice (mental & physical) with reminders (in written explanations + diagrams, or video) should help students (especially leaders) learn new patterns much more quickly.

MORE — In the future, I'll describe other ideas about techniques to improve efficiency and to achieve other educational goals.  One idea, outlined here very briefly, is that most rotation-patterns (and many other patters) are identical for leads & follows, they're just offset in time: what a leader does at one time, a follower does at another time.  Therefore, instead of wasting valuable in-class time by explaining each pattern separately, a teacher can have the entire class learning-and-practicing the same set of patterns.  Then dancers get together in couples, to practice doing these patterns as a two-person unit with leading-and-following, with the proper "offsets in time."  Later, I'll explain this dancing principle (and associated teaching strategy) more thoroughly, with examples & details, along with other techniques for teaching.

        Movements with Rhythm
        An essential skill for dancing is an ability to move in consistent rhythmic patterns, so your stepping-rhythm will match your partner's rhythm and (as explained in the next section) the music's rhythm.  The main way you improve this ability is to use it, with or without a partner.  It's easy to practice this in solo moving-with-rhythm, in free dancing without a partner;  just put on music with an appropriate tempo for a particular rhythmic pattern (the basics are described earlier) and practice keeping this rhythm pattern (in time) while (in space) you are moving in the wide variety of dance patterns (moving backward, forward, sideways to left or right, rotating left or right,... slowly & quickly, with short strides & longer strides) that might be used while you're dancing with a partner.
        This practicing is valuable for leaders and (especially) for followers.
        For leaders, it will help you avoid getting confused and mis-leading your partner by changing the dancing rhythm in ways that you had not intended, in ways that won't work with the physics-and-physiology of your confused partner.
        For a follower, you can practice moving in the many possible ways that you might be led while dancing, so you can cope with “whatever happens” without taking extra steps.  For a novice, extra steps tend to occur because they help you keep your balance while moving in a dance pattern, in ways that cooperate with your physiology and minimize any potential for injury or “falling down” embarrasment.  These extra steps are the natural way of moving that you have practiced your entire life.  To overcome these instincts, you must practice a new way of moving gracefully and confidently in new time-and-space ways, with complex dance-patterns and a consistent rhythm.  The movement-practice I recommend can help you do a wider variety of movements without extra steps, so you can maintain the rhythmic step-pattern.
        This is an important skill.  When I returned to dance-leading in 2012, one of my discoveries is that many followers simply cannot “keep the rhythm” consistently, so they have no chance of consistently following my leads, or those of most other leaders.  If you want to become a reasonably skilled follower, keeping the rhythm-pattern is a minimum requirement, a basic starting point.

        Dancing with Music
        Improving your musical skills will help you dance in ways that cooperate with the music.  When you and your partner each “feel the music” and are dancing with it, this makes it easier for you to dance with each other.
        At a basic level, you should learn how to recognize the 1-count of each musical measure, and know whether a measure has 4 counts (usually) or 3 counts (as in a waltz).
        At a level that's a little more advanced, but is easy when you become more musically aware, you can listen for the phrasing that occurs every 2 measures.  In 4-count music, 2 measures is 8 counts, so coherent phrases — these are sort of like “sentences” in talking — occur every 8 counts, which is 2 measures.  Phrasing also occurs in multiples of 2 measures (so it's 2, 4,...) to form coherent “phrasing units” (analogous to paragraphs?) that fit together well, with a clear beginning & ending.  Of course, with 3-count music the 2-measure phrases begin every 6 counts.
        This 2-measure phrasing is important for dancing.  A 6-step dancing pattern requires 2 measures of music;  usually this is 8 counts, but it's 6 counts for a waltz.  A leader should begin a 6-step pattern at the beginning of a 2-measure phrase.   /   In terms of priorities, it's most important to begin a 6-step pattern on the 1-count of a measure.  It's less important, but still is important, to begin at the beginning of a 2-measure phrase.  These two beginnings (on the 1-count of a 2-measure phrase) make it easier for your partner to follow your leads, because she can stay in-sychronization with you and also with the music.  When this threesome (music, leader, follower) are all in-synch with each other, your dancing will feel better (for both of you) and (for spectators who know music & dancing) it will look better.
        Phrasing is less important with 4-step patterns.  If you begin on any 1-count, your 4-step pattern will work with (“quick quick quick quick”).  And you alternate between starting on the 1-count & 3-count if it's done in 6 counts (like “slow slow quick quick”) because with 4 steps in 6 counts, the beginning of a 4-step pattern shifts back and forth between the 1-count and 3-count, and of course this cannot be avoided.  With 4 steps in 4 counts, almost always (unless you have a good reason for the shift) you should begin a pattern on the 1-count.
        These principles are generally accepted.  But there is a range of opinions for some principles, regarding a Matching of Styles - Music and Dancing.

        Principles for Transfer of Learning
        Some basic principles, including principles for skillfully doing rotations (of 180°, 360°,...) and other types of movements, will help dancers (especially leaders, but also followers) transfer what they learn from one dance to another.  This is consistent with research-based principles for transfer of learning, such as using Conditional Knowledge & Organized Knowledge and much more.  Here are some useful principles:
    • Basic principles of rotation — it's easier and more “natural” to begin turning left when stepping forward on your left foot or backward on right foot, and begin turning right when stepping backward on left foot or forward on right foot — can be used in all dances.  And students can learn special techniques (pivots, step-behinds,...) for other kinds of rotations in turns or semi-turns.
    • Also, when you and your partner are facing each other, the kind of turn that is “natural” for a leader is also best for the partner.  But if you're facing the same direction, as in a cuddle or sweetheart position, you must choose who will do the easy turn, and it's courteous for you (as a leader) to make things easy for your partner, while you use a “special technique” to make it also work for you;  doing this is challenging for a leader because you must do the opposite of your habits for “doing what is natural” that you have established through practice.
    • If you are facing your partner but she is “offset” to one side, you can rotate in one direction but not the other;  if during a rotation you will face each other, the turn will work, if not it won't.  For example, if she is offset to your left, during a left-rotating turn you will face each other and it will work.  But if she is offset on the right side of you, a right turn will work.  There also are principles for moving diagonally forward in the line-of-dance, first on one diagonal and then on the other diagonal, making forward progress in a zig-zag “sideways W” pattern by using quarter-turns.
        All of these principles, and more, can be taught using a combination of logic (based on principles of physics-and-physiology) and experimenting (you try things and observe how well they work) along with letting your body-and-mind “figure out the details” as with "inner game" approaches like the one in my paragraph about analysis-and-synthesis of juggling.

I.O.U. — More could be said in each of these paragraphs, and others, but that's all for now.  Also, above you'll find Rhythms and Variety in Leading (with some surprises) and Variety in Styling and below, Matching Styles and Hybrids.

 


 

a personal history of
my Learning and Teaching

        During a two-year period in 1992 to 1994, I did a lot of ballroom/swing dancing, including lessons from many different teachers, first in Madison, then in Seattle for Summer '93, and back in Madison.  I learned from all of them, about dancing and also teaching.  Then I combined these ideas about learning-and-teaching with ideas from other contexts, and I thought about how to combine what I was learning into a course.  The main objective I wanted to achieve was helping leaders (and followers) learn many new patterns quickly and well, mainly by using transfer-of-learning, but also by developing improved techniques for teaching patterns.
        Some of these ideas are summarized in pages written for class proposals in March 1994 and August 1994.  Neither was accepted (in fact, I think the second was never even read-and-considered, in a one-person decision based on minimal knowledge) so I've never taught any formal classes, although I have done some informal “teaching” with friends.   /   From 1995 thru 2011, I danced ballroom occasionally but not often.  In mid-2012, I again began dancing a lot, and thinking about teaching, but only did a little teaching.

        AFAIK, an emphasis on “teaching for transfer” (it's my emphasis in this page) isn't common among teaches of ballroom.  One exception I know (and certainly there are others) is Victor Eijkhout – compared with me, he is “more expert” as a teacher of dancing-and-music – who independently discovered the principle of pattern-transfers, saying "There are a few implications to all these resemblances [between the QQS/SQQ rhythms of different dances]:  You can steal moves from all these dances for your two-step material. ..... You can dance two-step to other kinds of dance music that have the right tempo. ..... You can dance other dances to two-step music."
