Perhaps, but as a sus chord has no 3rd- and thus is not major or minor- specifying it as maj(sus) or min(sus) would be confusing in performance (note that I play jazz and it is not uncommon to receive a chart about 5 seconds before downbeat. Anything can be explained and resolved in rehearsal, of course). Given an Am(sus) chord on a chart I would wonder whether the composer wants a suspended chord (A D E) or a triad with a 4th- or much more likely 11th- added (A C E D). Adding the maj or min specifier adds confusion because I am forced to second-guess compositional intent in real time. The inclusion of the C could be consonant or dissonant- if, for example, the melody note is a B in the same octave then there is a minor 2nd- and either effect may be desired. With the chord Asus I am sure that the notes A D E are called for. I can tell from the rest of the music what the function of the chord is and what the resolution will be. >> Flexibility is one of the strengths of Lilypond. > > Precisely! _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org https://lists.gnu.org/mailman/listinfo/lilypond-user
