Gibb Sahib - I think I mentioned somewhere that I don't know much about Eastern music. I just hooked onto something I had read regarding Turkish musicians recently and overgeneralized it I guess. Anyway it wasn't an important point.

Then I thought a while about tablature for keyboard instruments, and I think it would look like the piano-roll view in a Midi sequencer, not like a staff. Not very readable, at least in real time.

In fact the general compromise with notation systems seems to be that the more accurate you try to make it, the less human readable it becomes.
