I like the thrust of your notation software. As a pianist, I'd
like to make a
comment on what I would like to see. Although the traditional
method of marking
accidentals works, it can be time-consuming to figure out whether a
note is to
be played as an accidental and this is often time a pianist does
not have. I'd
like to have my music all colour coded: naturals should be in
black, sharps in
some other colour, perhaps red, and flats in maybe green (double
sharps and
flats are rare and could be done in black or a different colour).
Then I would
not have to figure things out. This colour coding could be added
to normal
notation without changing the traditional aspects.
As an alternative to colour coding, it might be possible for the
note heads to
be different shapes for accidentals. These differences might be
too small to
notice at pace though.
