Hierarchy of Advancement Workshop Nine

Introduction
A heavy dancer. A light dancer. A deep action. A light action. A heavy groove. A light groove. What do these mean? Which properties are good and desirable? Which ones not so? How did these metaphors come about?

Concept: Apparent weight (Dance)
(Not to be confused with apparent weight in physics)
  • Manoeuverability - This is the second-party i.e. dance partner's perception of: how capable a dancer is of movement; how much lead force is required for, or provided by, movement and the cessation of movement.
  • Rhythmicity - This is the second-party i.e. dance partner's perception of: how capable a dancer is of interpreting rhythm with his or her body.
 Section I - Manoeuverability

Concept: The centre of gravity and basic divisions of the foot
The centre of gravity is the single point associated with an object where the force of gravity can be considered to act. Four parameters - front, back, medial (towards the centreline), and distal (away from the centreline) - coarsely divide the foot into four sections through which a dancer's centre of gravity appears to act. At which point the centre of gravity acts through the foot affects, profoundly, a dancer's ability to utilise force for motion.

Exercises: Kinesthetic detection of the position of the dance partner's centre of gravity, two-footed
Partnered. Double-hand hold, eyes closed. Weight evenly distributed across both feet. Centre of gravity acting through front or back of foot. The leader moves the partnership hand-hold gently and firmly away and towards his/her body, sensing the changes in contact pressure; the follower varies the exercise by changing from weight toe-ward to weight heel-ward. (An advanced practice involves the follower moving his/her weight toe-ward on one foot and weight heel-ward on the other foot.) How does the each partner perceive the 'lightness' or 'heaviness' of the other?

Exercises: Kinesthetic detection of the position of the dance partner's centre of gravity, single-footed

Partnered. Double-hand hold, eyes closed. Follower's centre of gravity acting through any quadrant of the supporting foot. The leader moves the partnership hand-hold, gently and firmly, away and towards, to the left and to the right of his/her body, sensing the changes in contact pressure. The follower varies the exercise by changing the quadrant through which his/her centre of gravity acts. How does the each partner perceive the 'lightness' or 'heaviness' of the other?

Exercises: Kinesthetic detection of the position of the dance partner's centre of gravity under turning, single-footed

Partnered. Single-hand hold, eyes closed. Follower's centre of gravity acting through any quadrant of the supporting foot. The leader executes HALO turns (see: http://www.salsa-merengue.co.uk/VidTutor/merengue/halo_fol/int_halo_fol.html) sensing the changes in contact pressure.

The follower varies the exercise by changing the quadrant through which his/her centre of gravity acts. The leader varies the practice through choice of HALO direction and height. How does the each partner perceive the 'lightness' or 'heaviness' of the other?

Concept: Mode of movement (Dance) and a mode library
Parameters, such as the part of the foot through which a dancer's centre of gravity acts, profoundly influence a dancer's quality of movement; and how it is perceived by his or her partner, and even onlookers. A dancer can configure a mode of movement through the setting of these parameters and proceed to building a library of modes, from which may be selected the most musically appropriate at any time.

Exercises: A simple mode, full dance context
Partnered, to music. Deploying a simple, single-parameter, mode: selecting which point of the foot through which the centre of gravity acts; in full dance context.

Section II - Rhythmicity

Concept: 'Depth of penetration' of weight into the dance floor
This is a progression with pedalling, based on its learning metaphor of 'pressing a nail into the floor' (see 'Learning Tips' in http://www.salsa-merengue.co.uk/VidTutor/merengue/lbaction/det_lba.html). To 'drive the nail deeper into the floor', the dancer smoothens and slows the pedalling action, taking up more of the beat. To 'tap the nail onto the surface of the floor', the dancer shortens the time of the action.

Exercise: Salsa walk, 'driving the nail deeper into the floor'
Solo, then partnered. Kinesthesia - detect the tone and relaxation around the hip, and co-relate it with the intensity and progression of pressure registered through the soles of the feet. Does this groove feel heavier or lighter?

Exercise: Salsa walk, 'tapping the nail onto the surface of the floor'
Solo, then partnered. Kinesthesia - detect the tone and relaxation around the hip, and co-relate it with the intensity and progression of pressure registered through the soles of the feet. Does this groove feel heavier or lighter?

Concept: Lower body action (pedalling) affects rhythmicity
The 'depth of penetration' of weight qualitatively affects two aspects of the lower body action: attack i.e. how rapidly the heel contacts the floor; and duration i.e. the breadth of time over which weight is transferred. Both of these are parameters in percussion and by extension, rhythm.

Exercises: A simple mode, full dance context
Partnered, to music. Deploying another simple, single-parameter, mode: selecting the quality of lower body action; in full dance context. An advanced variant is to deploy a different mode per leg.

Exercises: Compound modes
Solo, then partnered. What are all the possible modes which can be created when two parameters: where the centre of gravity acts through the foot; and quality of lower body action, interact?

Section III - Modes in practice

Exercise: Compound modes to music, solo
Solo, to music. This is an action-event practice: deploying modes of movement to music and assessing their musical qualities.

Exercise: Compound modes to music, partnered
Partnered, to music. This is an action-event-partnership practice: deploying modes of movement to music, assessing their musical qualities in first and second person, and understanding how modes influence apparent weight (and hence how others perceive you as a dance partner).

Hierarchy of Advancement Workshop Eight

Introduction
Building on the arm-functionality begun in the previous workshop, this session uses an actual flamenco rhythm interpreted on the hands in synchrony with lower body movment. More complex body isolations and arm positions are detailed.

Section I - Basic flamenco castanet rhythm

Warm-up reprising Exercise: A basic hand and foot rhythm to Nuevo Flamenco
Solo. Basic rhythms on castañuelas (hands) and zapateo (feet). All wrist gates.

Concept: The basic flamenco castanet rhythm
Left hand is the time-keeper; and
Right hand plays the roll from little finger to first finger.

Exercise: Basic flamenco castanet rhythm co-ordinated to a simple walk
Solo. Basic flamenco castanet rhythm on castañuelas (hands) and walking (feet). Heart wrist gates.

Exercise: Basic flamenco castanet rhythm co-ordinated to a simple walk, to music
Solo, to music. Basic flamenco castanet rhythm on castañuelas (hands) and walking (feet). Heart wrist gates.

Section II - Lower body action

Concept: Knees as regulators of the lower body action
The rate of extension of the knee joint is critical to the timing of weight transfer; its alignment with the heel and the hip determines the nature of the hip deflection: whether achieved through muscle tension or relaxation. And yet is probably the most overlooked aspect of the lower body action. As salsa dancers are least likely to be developed with respect to the proprioception and cortical mapping of the knees, the final section of basic lower body action will address this.

Exercise: Pedalling revisited
Particular emphasis on the smooth, horizontal plane, backward travel of the knee joint. Detecting the initial effect of the backward travel of the knee by sensing pressure on the sole of the supporting foot. Detecting the advancing effect of the knee by detection of pressure and displacement around the hip joint.

Exercise: Pedalling to flamenco castanet rhythm, static
Synchronising the pedalling action to the basic flamenco castanet rhythm:
heel - knee (commence) - knee (continue) - knee (complete) - hip

Exercise: Pedalling to flamenco castanet rhythm, walking
Without, then to music.

Section III - Compound body movements, horizontal plane

Practice: Body isolation exercise, seated, upper body (torso), compound circular paths
Figure-eight motif e.g. centre-west-centre clockwise one rotation, centre-east-centre anticlockwise one rotation. Repeat. (Note: Inverting the direction of rotation i.e. anticlockwise and then clockwise creates the reverse figure-eight.)

Practice: Body isolation exercise, seated, upper body (torso), compound linear-circular paths
Horizontal-plane loops e.g. north-west linear to north, full clockwise circle plus 90degrees to east, linear to south-east.

Practice: Body isolation exercise, seated, upper body (torso), compound linear-circular paths
Vertical-plane loops - "rocking the cradle".

Likewise:

Practice: Body isolation exercise, standing, lower body (pelvis), compound circular paths
Figure-eight motif e.g. centre-west-centre clockwise one rotation, centre-east-centre anticlockwise one rotation. Repeat. (Note: Inverting the direction of rotation i.e. anticlockwise and then clockwise creates the reverse figure-eight.)

Practice: Body isolation exercise, standing, lower body (pelvis), compound linear-circular paths
Horizontal-plane loops e.g. north-west linear to north, full clockwise circle plus 90degrees to east, linear to south-east.

Practice: Body isolation exercise, standing, lower body (pelvis), compound linear-circular paths
Vertical-plane loops - "rocking the cradle".

Learning point:  Side-of-hip points to little toe
Observe that the lateral mobility of the hip is constrained by the supporting joints beneath it; the ankle and the knee. A general, though not absolute, guide is that 'the side of the hip should point to the little toe of its supporting foot' when that side of the pelvis laterally rotates to its forward-most position.

Concept: A fundamental difference between rumba and son action
The 'side of hip to little toe' phenomenon is used in defining the movement characteristics of rumba and son:
  • rumba action has less foot turn-out and hence the hip rotations are further forward, resulting in an even 'figure-eight' pelvic movement-path when viewed from above.
  • son action has more foot turn-out and hence the hip rotations are hardly forward, resulting in an asymmetrical 'figure-eight' pelvic movement-path which is flattened on the frontal side (facing the partner) when viewed from above.
Section IV - Arms

Concept: Constraints of the castanet positions
Having to hold the castanets from audience view behind the hands of the dancer, limits the distance which the castanet arm gates can be located distal from the body's centreline - the wrist of the outer arm can only bend inward so far.

Concept: Fan and skirt gates
Gates more distal from the centreline can be defined, and understood more easily, with the hand fan and the skirt. If necessary, a cape can be substituted for males.

Concept: Inner gates, castanets. Outer gates the fan and skirt/cape
These constructs determine the spatial location of the limbs and the routes of travel they trace. Additionally, they determine the conformation/shape of the hand(s).

Exercise: Positioning the arms through the external gates
Upper (fan), upper-outer (fan), outer (fan or skirt), lower-outer (fan or skirt) gates

Section V - Guaguancó fundamentals

Concept: The elemental guaguancó dance rhythm
The basic dance rhythm is a regular one alternating between unaccented and accented beats. This is translated into movement as step-accent-step-accent-(repeat).

Concept: The basic guaguancó movement mode is lateral
The functional constraint of the male having to circle around the female, yet still facing her, results in the foundational movement being laterally-based. Culturally the definition of the circle is important as it represents the circle of creation. Guaguancó is classic pursuit-and-capture.

Exercise: Basic guaguancó walk
Solo. Lateral movement. Side-tap-close-tap-(repeat).

Exercise: Basic guaguancó walk
Solo, to music. Lateral movement. Side-tap-close-tap-(repeat).

Hierarchy of Advancement Workshop Seven

Introduction
Current arm work is dominated by the 'styling' approach, whose emphasis is solely aesthetic, and is divested of its underlying tenets of physical functionality. This workshop takes a historical and cultural route to arm positions and movement, as a counterpoint to the styling industry. We also consider how the principles of arm-flow differs in performers with above-average limb-length, and how these are reflected in the strategies they employ.

Section I - Arms

Concept: flamenco's gates
Adapted for Afro-Cuban dance. Spatial way-points for the passage of wrist and elbow joints. Gates explored (wrist): hip, centre, heart, crown and high. The importance of developing cortical mapping, spatial mapping, and proprioception.

Introduction to flamenco's castañuelas
Adapted for Afro-Cuban dance. Deploying castanets as a means of providing auditory feedback for the (unsighted) positions of upper limbs in space and time.

Exercise: A basic hand rhythm to Nuevo Flamenco
Solo. A basic rhythm interpreted on castañuelas, wrists at the heart gate.

Exercise: A basic hand rhythm to Nuevo Flamenco
Solo. A basic rhythm interpreted on castañuelas, wrists at the central gates.

Exercise: A basic hand rhythm to Nuevo Flamenco
Solo. A basic rhythm interpreted on castañuelas, investigating all remaining gates.

Concept: flamenco's zapateo
The practice of zapateo [foot-tapping] as a means of providing auditory feedback for the (unsighted) positions of the lower limbs in space and time.

Exercise: A basic hand and foot rhythm to Nuevo Flamenco
Solo. Basic rhythms on castañuelas (hands) and zapateo (feet). All wrist gates.

Concept: gate linking
The flow, control and angles of the arm-joints as they travel through the various gates perform the functional and aesthetic characteristics of the dance.

Exercise: Offerings on saucers
The parameters of the start positions are: right hand or left hand or both; clockwise or anticlockwise; above or below the shoulder. The objective is to keep the saucers as level as possible throughout the movement, keeping the travelling smooth, even, passing through all the relevant gates, and maintaining an upright torso as far as possible.

Section II - Torso

Concept: finishing the compass points
Compound action of previous torso exercises to achieve linear and circular movements

Practice: body isolation exercise, seated, upper body, north-east to south-west

Practice: body isolation exercise, seated, upper body, north-west to south-east

Practice: body isolation exercise, seated, upper body, compound linear paths
Linked X forms e.g. north-west, north-east, south-west, south-east, north-west. Repeat.

Practice: body isolation exercise, seated, upper body, circular
As per: http://www.salsa-merengue.co.uk/VidTutor/bodyskills/chest_movement_circular.html

Concept: rhythmic changes in movement
The 'push-pull-push' or 'chachachá' movement variation, especially in the linear paths.

Practice: body isolation exercise, seated, upper body, all linear paths, chachachá variations
Substitution of chachachá rhythmic movement variation in all linear path exercises.

Dance Ethnology Distilled

"Dance sets politics in motion, bringing people together in rhythmic affinity where identification takes the form of histories written on the body through gesture."
