As a starting point, we got a working implementation of playing the melody of "Twinkle Twinkle" only on the right hand.
As a followup, we implemented two hand movement and got the single note melody playing on the right hand while the left hand played a single chord. Each note is played with the same chord simultaneously. The only chord handled, in this case, is the C-G chord.
The final product! The right hand plays the single note melody while the left hand plays variable chords. The left hand can handle variable length note differences in the chords by adjusting the degree to which the gripper is open. For example, a 4-note chord such as C-F and a 5-note chord such as C-G are both handled.
