This is shown in figure 3a. One wholetone scale is fixed and the other is rotated in a counter clockwise direction one note at a time. After each rotation, the distance the hand travels is compared with the previous rotation. Rotating the wholetone scale in this manner will provide consistent diatonic scale patterns. The distance the hand travels is less when the notes are as shown in figure 3d.
Further rotation increases the distance the hand travels.
The interesting feature of figure 3d is the grouping of the naturals along the F-B tritone line. To make use of this grouping, the single will be positioned with the sharps and flats in the upper half of the pan. After some analysis and experimentation the unique arrangement was found when the pans are arranged with the sharps and flats in the upper half of each pan and the pans positioned such that the interval of notes on adjacent pans form a fifth in the clockwise or counter clockwise direction. With the exception of the sextuple, all major scale patterns are obtained with minimum hand movement. On this instrument, with the minimum interval of a tritone on each drum, the notes for any major scale are located on all six drums, causing large hand movement.
