Introduction:

Numbers structure time and space.
Geometry is numbers in space.
Rhythm is numbers in time.

0.5C0R35 is executing these very simple concepts, using the body as a tool of measurement, a rhythm generator and a medium for the time and space patterns of these numbers.

Tools:

The body.
Chalk.
White masking tape, 50m on 19mm.

*** of course, if you prefer you can use another colour or type of tape.

The base:

A surface from 1m x 1m to 3m x 3m or more.
The possibility to draw with chalk on this surface.
The possibility to use masking tape on this surface.
A circle.
The concept of counting in regular pulsation.

Preparation exercises (Base, preparing & tuning):

1 – “Geometry is numbers in space.”

Choose a point on the floor and mark it with the chalk (X). We are going to call the centre of our circle point 0.

• Your elbow, hand and forearm will be our compass drawing tool.
• We are going to draw a circle with the chosen point 0 as the centre of the circle.
• Its radius (R) will be the length from your elbow to the chalk in your fingers.
• This we will name point 1.
• Put your two knees in the floor.
• Go down with your upper body to put your right elbow on point 0.
• Put your arm lower until the chalk touches the floor at point 1.
• With your left hand, support the weight of your body so your weight is not on the elbow of your right hand.
• Contract your abdominal muscles to connect your upper and lower body. Stay connected with your feet, your spine and hip and keep moving your head (eyes) to check between point 0 and 1 and the arcs.
• Release your right shoulder joint but keep a shape or a form. It should feel like your right arm is segregated from the top of the humerus, so that you can turn your whole arm from that point while keeping the rest of your arm in the shape as much as you can.
• Try to make a quarter circle from point 1 to your left, while only turning your arm from the top of the humerus. Keep your elbow on point 0.
• Recheck your elbow’s position in relation to point 0 and restart the same process for a second quarter circle. Then add a third quarter and a fourth one.
• Now you have your circle. Mark point 0 and point 1 again, we will need them for what is following.

2 – “Rhythm is numbers in time.”

• Choose a metre with a tempo or speed at which you feel comfortable. A metre could be a 3/4s bar or 4/4 or 5/4,…for example.
• Practice the metre in your head, while clapping or by stomping the pulse with your feet.
• Use your two hands or your two feet separately to do both, metre and pulse, to warm up the coordination of your right and left brain.
• Use your hands to make the metre on your thighs, on your chest or on other parts you feel comfortable with.
• For practicing coordination, make a beat with each hand or foot. Repeat it one or multiple times with all the bars of the rhythm audible. Count on 1, on 2, on 3, on 4, on 6, on 8.
• Keep the same rhythm internally. Make the beat audible with your hands or feet, but only on the 1 of each bar.

Plans & constructions:  

We are going to use these base elements to construct geometric patterns with numbers (1, 2, 3, 4, 6, 8), while simultaneously exercising them rhythmically.

• To write our rhythms we are going to use:

(O) to symbolise the audible beat of each metre. (the “1”)
(.) to symbolise the non-audible parts of the metre, the continuous pulse.

Example:
The metre in 4/4 will be written : O . . . O . . . O . . . O . . .

metre in 1: O (= “1 1 1” etc.)
metre in 2: O . (= “1 . 1 . 1 .” etc.)
metre in 3: O . . (= “1 . . 1 . . “ etc.)
metre in 4: O . . . (= “1 . . . 1 . . . “ etc.)
metre in 6: O . . . . . (= “1 . . . . . 1 . . . . . “ etc.)
metre in 8: O . . . . . . . (= “1 . . . . . . . 1 . . . . . . . “ etc.)

• To write our drawing bases we will use:

R to symbolise the Radius.
Radius = from your elbow to the chalk ≈ your forearm and hand

In the figures down below I use ( – – – – ) to symbolise the non-visible part of the drawing.
– ( – – – – – – – – ) = R

Figure 1  

• Center 0.
• Start the circle from point 1.
• Divide the circle on 2.
• Divide the circle on 3.
• Rhythm on 2.
• Rhythm on 3.

Figure 2 

• Divide the circle into 2 equal parts:

From point 1 pass through the centre with a line up to the point where it crosses the circle again at point 2.

Rhythm on 2: O . O . O . O .

• Divide the circle into 3 equal parts:

Put your elbow on point 1 and make an arc that crosses the circle one time.
Put your elbow on the point where your arc crossed the circle and repeat the same by making an arc that crosses the circle at a third point. That is point 2, it  divides the circle into 3 parts.

Repeat this one more time until you get 3 points.
Now you have points (1.2.3)
*see figure below

Rhythm on 3: O . . O . . O . . O . .

Figure 3  

• Divide the circle into 4 equal parts:

Rhythm on 4: O . . . O . . . O . . . O . . .

Figure 4 

• Divide the circle into 6 equal parts:

Rhythm on 6:

O . . . . . O . . . . . O . . . . . O . . . . . O . . . . . O . . . . .

Figure 5

• Divide the circle into 8 equal parts:

Rhythm on 8:

O . . . . . . . O . . . . . . . O . . . . . . . O . . . . . . .
O . . . . . . . O . . . . . . . O . . . . . . . O . . . . . . .

Figure 6  

• Divide the circle into 3 and 4:

Polyrhythm of 3:4

O . .  .  O . . . O  . . .
O . . O . .  O . . O . .

Figure 7

• Divide the circle four times into 3 and three times into 4. Divide the circle 4×3 & 3×4 = 12 equal parts.

Polyrhythm of 2:3:

O .  . O  . .
O . O . O .

Polyrhythm of 3:4:

O . .  .  O . . . O . . .
O . . O . . O . . O . .

Polyrhythm of 6:8:

O . . . . .  . . O . . . . . . . O . . . . . . .
O . . . . . O . . . . . O . . . . . O . . . . .
