Re: pitch of notes when staff-lines = 1

Hi,

In percussions staves we need lines, spaces, but also note head and
articulation to indicate which note is played on which instrument.
For exemple Hit Hat is generally notated on G5 with three different note
head (open/half open/closed) and on D4 (played with pedal).
The snare drum commonly use three note head (hit, rimshot, side stick) on
C5 or B4 (Berkeley/Agostini)
It could be nice is a percussion set notation mapping could be define in
the staff ({instrument, technique} => {pitch, articulation}) and then
referring to this mapping in the note element.
This kind of "percussion staff tuning" could add the missing semantic on
percussion staves.

Sorry if that point was already discussed in the past.

Kind Regards,
Nicolas.
