Range of a piano: keyboard vs staves

Question

This is a kind of follow-up to this question. I'd like to reproduce with tikz the following image.

I have no idea of how I could "synchronize" the output of musictex and tikz. Maybe I'd better stick with tikz but then I don't know how to draw realistic notes, staves and keys (borrowing them from musictex)?

Here is what I've done so far in tikz.

    Black/.style = {%
      fill = black,

Answer 1

Not properly worked through, but hopefully shows how to "integrate" (in a very loose sense) musixtex and tikz.

EDIT: added keyboard and tonic sol-fa labels. Still a bit of mess though.
