[Help-gnu-music] How to typeset this?

[Stefano Ghirlanda]

Hi everyone,
I would like to contribute to the Mutopia project with some guitar
music, but I have a major problem which I can't figure out how to solve in
mudela, and I couldn't find info on the mailing list archive or the
manuals and examples.

My first shot is JS Bach's Allemande from the lute suite BVW996. I attach
a jpeg of the first line. My problems start at the last quarter of the
first full measure. One plays e16 g b e' but without stopping the strings
so that in reality the notes' durations are e4 g8. b8 e'16. In the
attached score this is indicated by having a beamed group of 4 16th notes,
of which three notes are duplicated stem-down with the prolonged
durations. My question is: do I really need 4 voices in mudela to achieve
this? Can't I say "print e4 but advance only s16" in the bass voice? Or is
there any construct especially designed for this purpose?

It seems to me, but I might be wrong, that mudela assumes that a Voice is
a continuous stream without overlapping notes. This seems a very
reasonable assumption, but it is rarely the case for the
guitar (and lute and friends), where resonances of previously played notes
make an important contribution to the music.

I welcome suggestions of an alternative notation, but the attached ones
seems to me the standard way of doing that...

Thanks everyone for your help,
Stefano
