The Bach-In-The-Mirror project is an example usage of my Mozart Tranposition Engine, which displays the 15 Two Part Inventions by Johann Sebastian Bach.
The app displays the inventions in all keys and with optional symmetrical inversion in each key.
The scores are produced with my Mozart Transposition Engine, are typeset with GNU Lilypond, and are designed to be used with my Kundalini Piano Mirror.
