DIAMETER OF EACH CIRCLE SECTIONED BY ITS RADIUS

The measurement of each radius around it own circumference divides the circumference into 6 equal parts...
Expansion or contraction takes place at each row according to measurement... The first section forms six rings... The seventh is a void of expansion as (RE) is 7/8... The eight, ninth and tenth row form a group of three... expanding and contracting simultaneously... The eleventh is void of expansion... The twelfth is (SOL) and (MI)
interchanging... The 13th and 14th form a wider void... The 15th and 16th form the diameter of the circle (TI sharp) or (DO flat).
