xpiano – An extension of the piano package

This package provides macros for typesetting virtual keyboards limited to two octaves for showing notes represented by a colored circle. Optionally, the number used for pitch analysis can be shown.

It is an extension of piano.sty by Émile Daneault, written in expl3 in answer to a couple of questions on TeX.StackExchange:

• https://tex.stackexchange.com/questions/162184/
• https://tex.stackexchange.com/questions/246276/.

It features extended syntax and several options, like setting the color, adding numbers for pitch analysis, one or two octaves, and others.
