Right. Why are we living with a notation which stopped growing about 150 years ago?

For example, as a person who uses lead sheets, I'm depend on knowing the chords for what I'm playing. When a note (quarter note or up) doesn't fit in the chord, I'm discombobulated. So what I do is take a yellow colored pencil and make a yellow splotch over the note. I chose yellow because the note has a lemony sour tang to it.

Another helpful thing was used in ancient manuscripts. It was called a custos and is a little squiggle at the end of a line to warn you that something strange is comin up, such as a big jump up or down. In the song "A Sweet Bunch of Daisies," which is in G, I use a custos at the end of a line to show that the next chord is an A, which you wouldn't expect.

And when a note is on a ledger line, why must the stubs of line which project from the notehead be so pitifully short? Is ink that expensive? I can hardly see them.

Pavane, if I didn't have a huge collection of music which depends on NWC, I would try your program.
