Perform expressions with the chord hand

Also, what about accidentals? Blues and harmonic minor scales seem like they'd be tricky if a given chord limits all notes to be within that chords implied mode. I wonder...playing say, a minor chord, how do you distinguish between the user wanting to play melodies in the aeolian vs the Dorian mode?

[...] it would be rad if you could use your left hand for expression. [...by "locking" the chord...] you could use all chord selector x and y translation for stuff like bends/tremolo/etc...

@zachkinstner response:

Regarding different modes and expressions with the left hand: In the video, I mentioned the "single row" of chord selections, using the palm as the cursor. If that works out, it creates a good opportunity to use different hand orientations, hand motions, and even poses (like a fist, or fingers apart, or fingers together).

In addition to bends and tremolo effects mentioned above, possible expressions could be:

• a "muted" style (where, on a real guitar, the hand rests on the strings while strumming)
• a "chicka" style (for playing "Smells Like Teen Spirit", of course)
