<p><b>The time-varying angular positions of the MCP, PIP, and DIP joints of the index, middle, ring, and little fingers (upper panel) and time-synchronized MIDI datasets representing the moments of tone onset (MIDIon) and offset (MIDIoff) at each of eight keypresses</b>. For the upper panel, the y-axis is a joint angle of the fingers in degree.
