Figure 4

One cycle of the melody performed by S24 at 11.7 tones per second. Top panel shows the fingertip trajectory for the middle finger (finger 3); the middle panel shows the finger joint angle trajectories (in degrees) for the metacarpophalangeal joint, MCP (red line), the distal interphalangeal joint, DIP (dotted blue line), and the proximal interphalangeal joint, PIP (dashed, green line); the bottom panel shows wrist angle (purple solid) and wrist rotation trajectories (orange dotted). Thin vertical lines in the top panel indicate the tone onsets (KBs) of the 8 tones of one cycle of the melody as printed in music notation above the figure.
