Synchronous Rhythm And Autonomous Rhythm In Equilibrium

Last Tuesday's solares began not quite as well as I would have liked.

It was supposed to start off with a simple warm-up of son montuno maracas rhythm, "slowandslow" embodiment rhythm variation, and infinity engine; and build from there. What I got instead was one out of three: the "slowandslow" embodiment rhythm variation. The infinity engine was a no-show. More disconcertingly the maracas strokes were played in direct correlation (1:1) with the embodiment rhythm instead of the proper twice the cycle speed.

Evidently the participants had failed to invest in themselves with practice. But at least they were honest about it. There was nothing to be gained from anything other than turning the workshop into an extended practice session. So I shelved the intended content and designed the practice session on-the-fly. For the practice session to be useful, it could not be a dry punitive exercise in drudgery; that would hardly be an incentive for later self-practice. The session needed to be interesting and challenging and rewarding.

A deeper evaluation of their proficiencies was needed, so I asked them to perform the embodiment rhythm and the son montuno maracas rhythm without music. It didn't take long to see that participants:
  • were unaccustomed to playing on their own;
  • relied on music as a crutch; and
  • had never listened critically to the musicality of their playing i.e. it was purely mechanical in sound production.
These characteristics are not uncommon in developing percussionists. Therefore what had to be done next was principally well-established: to increase the quality of execution by improving musicality. The novelty was that I would use a balance of synchrony and autonomy exercises to achieve it. Synchronous practices would help diffuse my playing expertise through the group. Autonomous practices would promote the sense of individual ownership over their playing.

Synchronous Practices

Exercise 1: Side-by-side, facing the same direction
Paired practice. No music. Caribbean sway. "quick, quick, slowandslow". son montuno maracas rhythm. Changing partners at each iteration.

I deliberately didn't specify whether to execute this in phase or not, so participants freely experimented. Participants noted that their ability to synchronise with their partners improved with each iteration. When they partnered with me, their phrasing improved and their maracas began to sound less mechanical and more musical.

Exercise 2: Side-by-side, facing the same direction, "front" cue
Paired practice. No music. Caribbean sway. "quick, quick, slowandslow". Son montuno maracas rhythm. Changing partners at each iteration. One partner designated static, the other moving.

With the "front" cue, the designated participant moves from the side position to in front of and facing their partner.
With the "side" cue, the designated participant returns to the side position.

This exercise introduces perturbation by requiring movement and the suppression of mirror neuron stimulus in the face-to-face position. With respect to the latter: all participants were dextral, and as a result, a mirror image cannot be maintained between partners' hands when they faced each other.

Participants were given the scope to explore the effect of phase under their own initiative. Again, each participant's ability to maintain synchrony with their partner improved iteration upon iteration as they 'toughened up' against the disturbances (i.e. became more autonomous).

Briefing: concordance and opposition positions
Synchronous rhythmic activities are easier in the side-by-side 'concordance' position. There is less reliance on the visual sense and, consequently, proportionally more use of the aural and kinesthetic. Confusion due to mirror neuron activity due to asymmetry is also minimised. The converse holds when partners adopt the face-to-face 'opposing' position.

Autonomous Practices

Exercise 3: Side-by-side, facing the same direction, "turn" cue
Paired practice. No music. Caribbean sway. "quick, quick, slowandslow". Son montuno maracas rhythm. Changing partners at each iteration. One partner designated static, the other moving.

With the "turn" cue, the designated participant executes a half turn on the spot.

Partners begin by establishing synchrony. Upon issuance of the "turn" cue, the moving partner executes a slow half turn away from the static partner. This has the effect of decreasing the sound volume of their maracas (i.e. increasing autonomy) over the first quarter turn; and then increasing the sound volume (i.e. decreasing autonomy) over the second quarter turn.

Some participants experienced a sensation of 'tension synchrony' as if they were pulling against elastic when they turned away, and the elastic tension dissolved when they turned back to their starting position.

Briefing: "what's autonomous?"
Participants where not clear on the property of autonomy. This was because the requirement for autonomy is fleeting with Exercise 3 when the designated partner turns away from the static partner, presenting her/his body as a sonic baffle. The presence of 'tension synchrony' may have masked the sense of autonomy. I had a more involved exercise which would clarify that...

Exercise 4: Side-by-side, facing the same direction, "turn-back-turn-front" cues
Paired practice. No music. Caribbean sway. "quick, quick, slowandslow". Son montuno maracas rhythm. Changing partners at each iteration. One partner designated static, the other moving.

With the "turn" cue, the designated participant executes a half turn on the spot, to face the opposite direction
With the "back" cue, the designated participant moves diagonally-forward into a back-to-back position with the static partner.
With the "turn" cue, the designated participant executes a half turn on the spot, to face the static partner's back.
With the "front" cue, the designated participant moves diagonally-forward to their original start position.

Autonomy is explored:
  • symmetrically after the "back" cue when both partners are unable to hear each other; and,
  • asymmetrically after the second "turn" cue when the static partner can hear the moving partner but not vice versa.
Conclusion

At the end of the session, participants felt that they:
  1. were playing more musically;
  2. understood each other's music-making personality better;
  3. were more capable of synchronising to others; and
  4. had greater autonomy and thus were less perturbable.
This session served as a taster in the delicate power possible when synchronous rhythm and autonomous rhythm are held in balance.

Despite its inauspicious beginnings, the outcomes in synchrony, autonomy and self-realisation were encouraging. I foresee that solares will adopt this tack for the next few weeks, so that the good work done so far does not go to waste.

Rhythmic Modulation

Exploring the phenomenon of timeline modulation was the theme this week's Solares. There are a number of forms it takes, so the definition of modulation in this workshop was:
"when the rhythm of one timeline is allowed to influence the rhythm another"
There were two rhythms at play,
  1. the standard unaccented embodiment rhythm (atiempo timeline); and
  2. the vocalised open ("gung-gung") and slap ("pak") tones of the tumbao moderno (contratiempo timeline).

Warm-up: Recap of Previous Content
Solo, without music. Caribbean sway basic. Begin with "gung-gung" vocalisation (beats 4,4+). Add embodiment rhythm (beats 1,2,3). Add "pak" vocalisation (beat 2).

Solo, with music. As above.

Observation Practice
Two participants were selected to demonstrate modulation. One had naturally allowed the "pak" vocalisation to modulate her embodiment rhythm, evidenced by a stronger, accented second step. Another, although performing the "pak" vocalisation, had naturally maintained three unaccented steps.

Exercise One
Solo, without music. Caribbean sway basic, then walking. Begin with "gung-gung" vocalisation (beats 4,4+). Add embodiment rhythm (beats 1,2,3). Add "pak" vocalisation (beat 2). Allow the "pak" vocalisation to 'colour' to the second step.
Learning point: "let the pak from your throat flow through your feet"

Exercise Two
Solo, with music, As exercise one.

Learning Concept
Participants were first encouraged to explore modulation as present (accented) or absent (unaccented). Then they were encouraged to explore it quantitatively as 'colouration' (i.e. modulation) using the metaphor of a volume control dial: zero being unaccented, ten being as accented as possible, then arbitrary values in-between e.g. five, three, seven.

Exercise Three
As exercise two. Application of learning concept. Participants were asked to determine which 'colour' dial setting was most appropriate for the music track being played.

Exercise Four
As exercise three, but partnered.

At this point, participants' quality of execution encountered a downturn. As the addition of a partner was the single additional parameter, I surmised that the challenge lay in the mutual negotiation of an appropriate modulation level. This was verified through questioning the workshop participants. Reading this - the negotiation of each individuals idea of appropriate modulation in a partnership - as being one variable too far, I determined to continue with the principle of the exercise but adapted to make it achievable.

Exercise Five
Partnered, to music. Caribbean sway basic. Tumbao moderno "gung-gung, pak" vocalisation.
I called out a number indicating modulation level (on a scale of 0-10) and each participant was to interpret it at individual level, and then negotiate it at partnership level.

Discussion
The initial exercises were met with varying success. This may have been due to either: a lack of skill in the execution; or a lack of understanding, given that modulation was a new concept. Both were equally likely.

Modulation is dependent upon the quality and strength of both signals: the embodied timeline and the vocalised timeline. If one signal timeline (in this case the vocalised one) fades in and out, and is temporally unstable, then the effect of modulation cannot be consistent.

Towards the end of the session (during exercise five) participants' dance rhythms were showing increasing signs of being affected by the "pak" accent, indicating that early-session low success was due to a lack of familiarity with the concept.

The introduction of additional structure through removal of one parameter (i.e. my setting of modulation level) suggests that more structured intermediate exercises might attenuate the steepness of the learning curve.

Conclusion
The indications are that a re-running of the content with additional support and fewer variables i.e.:
  1. externally set modulation levels;
  2. emphasis on individual exercises; and
  3. defined spatial configurations;
would provide an intermediate range of practice for the development of the skill of modulation.

The Fundamental Characteristics of African Dance

Index of the fundamental characteristics of African dance and derivatives. Derived from Welsh-Asante's seven characteristics of African dance in "Commonalities in African Dance: An Aesthetic Foundation" (1985).

1. Low to the earth
African cosmology regards the Earth as a benevolent world which sustains them, as compared to the European's place of trial to ascend from. Hence the characteristic of African dance is one which works with gravity, not one which seeks to defy it.

The 'Earth-Centred' Posture
With the ankles just inside one hip-width apart, and the body in a seated posture but inclined forward with knees flexed, this is a root position of West African dance. The posture places the dancer in dynamic equilibrium with gravity: energy from the dancer radiating downwards to the earth is in balance with the energy radiated from the earth upwards.

2. Undulating from the centre outward
(remarks to follow)

3. Polyrhythmic
(remarks to follow)

4. Emphasis on the pelvic girdle
(remarks to follow)

5. Body part isolations
Each body part tells its own story.
"All the elements of the music are displayed clearly in the body and nothing is left out." - Emily Willette (2012)

6. Whole foot touching the ground
(remarks to follow)
"We are the men of dance, whose feet draw new strength pounding the hardened earth." - Léopold Sédar Senghor (1945).
"stamping feet on the ground is a show of extreme joy" - Alphonse Tiérou (2000) 

7. Bent knees
(remarks to follow)
"dancing in a bent-over position with arms folded over the chest is a symbol of initiation" - Alphonse Tiérou (2000)

8. Texture
describes how dance functions as bodily (performative) conversation.
"Tell me how you dance and I'll tell you who you are." - Alphonse Tiérou (2000)
"When a body moves, it's the most revealing thing. Dance for me a minute, and I'll tell you who you are." - Mikhail Baryshnikov

"pak" - one syllable adds heart

(Addendum to the previous post.)

As Solares drew to a close, I surveyed the last exercise: the performance of a simple rueda de casino using the "pak" vocalisation. Standing beside me was an observing participant who said something poignant:

Participant: "It makes me very sad."
Me: "What's made you sad?"
Participant: "After all these years of dancing, you've made me realise that I was doing it mechanically."

He'd understood the artistic expression individually possible in the rhythm of salsa; a fact reinforced when the rueda began to gain rhythmic dimension as casineros got their heads around adding the presence of the "pak" syllable in their rhythm.

I was heartened. You can't ask more from an exercise than for it to unveil the body of art.

"pak"

True to my decision for a positive move to rhythm, I turned up to Solares armed with a learning game plan, a bagful of hand percussion, a compact conga, and a cajón. This approach to content - the meanings of rhythms to dancers - was new to Solares and although I had a direction, I couldn't anticipate the response nor outcomes, so I was loaded for bear.

There were two possible routes to take:
  1. picking one timeline class and investigating-developing it to its fullest extent in the time available, or
  2. skimming through the four timeline classes to give an overall feel for the rhythm capsule in ensemble.
I wouldn't know which route until I assessed Solares' participants response to the first exercise, which was designed as an indicator.

Background
Right from Solares' inception, the timing mechanism used has been based on the non-verbal vocalisation of the tumbao moderno's open tones "gung-gung" (beats 4 and 4+) either in full context of the music, synchronised to the actual open tones of the tumbao moderno played on congas by yours truly, or as a standalone rhythmic cue/timekeeper.

Backbeat Timeline: Tumbao Moderno rhythm
The lowest-hanging fruit was to explore the timeline in which the long-established "gung-gung" was a component - the backbeat* timeline. To put this more expressly, the tumbao moderno rhythm is an example of a backbeat timeline. To complete the timeline, all that was needed was the additional vocalisation "pak" on the European count of beat 2. Hence the vocalisation would be:

"gung-gung (4,4+), ... , pak (2), ..., gung-gung (4,4+), ... , pak (2), ..., " repeated

Exercise One
The Caribbean sway basic was used as the embodiment (i.e. dance) context.
  1. "gung-gung" vocalisation followed by three steps, to yield:
    "gung-gung", step, step, step.
  2. Then add the "pak" vocalisation synchronous with the second step:
    "gung-gung", step, "pak"step, step.
Results
All participants executed part 1 easily. But when it came to adding the "pak" vocalisation synchronous with their second step, they encountered difficulty. It took most of the workshop as learning time (with remedial instruction) to achieve independently reproducible practice. By default, Route 1 (above) became the course.

Participants' independence and reproducibility of practice was verified through the contrasting activity of incorporating the vocalisation in a simple rueda de casino comprising just basic guapea timesteps and dame partner changes.

Discussion
I believe two factors contributed to the unexpected initial lack of success.

1. The "gung-gung" had been interpreted as a component of the embodiment timeline, NOT as belonging to a separate timeline.
This meant that participants were only tracking one simple timeline. The addition of the "pak" forced the excision of "gung-gung" from the embodiment timeline into its proper backbeat timeline. Participants now had to track two timelines: the vocalised backbeat timeline and the stepped embodiment timeline. All-of-a-sudden, cognitive overhead had more than doubled since two timelines had to be maintained AND they had to be synchronised and merged to create a composite timeline**.

2. The "gung-gung" had been interpreted as a cue anticipating the beginning of the timeline NOT as the beginning itself.
The result, given that the human brain perceives regular meter as alternating strong and weak beats beginning with the strong***, was that the first and third steps coincided with the neurologically strong beats; the second step plus "pak", and the "gung-gung" fell on the neurologically weak beats.

Future Study
Participants' ability to track two separate timelines must continue to develop. This would allow for their merger to form a composite timeline yielding greater rhythmic stability; and an aesthetic investigation into what happens when a rhythm is allowed to modulate another rhythm.

A shift in the perceived start of the rhythmic timeline: from the first step to the "gung-gung" i.e. from the European to the African. To achieve success, "gung-gung" must be understood as important beats in their own right, not simply as cues to the (perceptually) more "important" beat of the first dance step. I think it likely that an interchanging dance-percussion ensemble format will be evaluated for its suitability.

Notes
*The online definitions of the backbeat expose the limitations of the internet as a web resource. For example, Wikipedia's (https://en.wikipedia.org/wiki/Beat_(music)#Backbeat) point to its origin as being in rock music, and FreeDictionary's (http://www.thefreedictionary.com/backbeat) limiting it as a characteristic of rock music. Neither mention its pre-existence in, for example, Senegambian music, nor trace how it came to be in rock music (see 'The Latin Tinge' by John Storm Roberts).
