We are talking about 7.5cm/octave here, so a horizontal escapement of 0.625cm per semitone. Since the notes are in staggered rows, the actual distance is more like that of horizontally adjacent buttons, namely 7.5cm/4 = 1.875cm but in a sort-of diagonal direction. > Also, one can switch fingers during an ornament, but I do not know if > it is done on accordions. Switching fingers is tends to be done more than on piano (even when using a piano accordion keyboard) since the instrument exposes the key release much more prominently than a percussive instrument like a piano does. It is more similar to harmonium and organ with regard to some articulation issues. Of course, a button provides a smaller area for switching. -- David Kastrup _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
