Jon-
THis looks quite plausible. A couple of questions:
a)is it a difficult task to link each tune to a program (Noteworthy, perhaps) that both plays the tunes and displays the notes?
b)How big a job is it to upgrade (additions and/or corrections)?
c) Is this strictly Web based, or can it exist as a stand-alone version? If the latter, what platforms will it run on?
d) How big a job was it to do the conversion (is it sufficiently automatable to permit frequent upgrades?)
