I recently discovered a new web-based music-notation program that you might be interested in: Noteflight.com. I got a free account, which allows you to do a lot; paid accounts are $50/year. (I have no relationship with the website, I just found it pretty amazing.)

For my own purposes, I created several different scores for the Fuhrman Tanz, which you can find here:

Guitar part only
Guitar part only, but with instrument changes
Guitar + accompaniment
Guitar + accompaniment + flute (A1, B1) + clarinet (A2, B2)
You can listen to each score in your browser by pressing P (or by clicking above the measures or selecting "Play" from the app menu).

These scores are pretty crude, and I had to do some inelegant things to get the output I wanted (e.g., I put far more dynamics notations than you'd put in an ordinary score, and I manually repeated the music rather than using repeat symbols, to allow me to create variation on the repeat).  They're also faster than the CD version (though it's easy to change the score's tempo, and you can change the playback tempo with a control at the bottom of the web browser, regardless of the score's tempo).

My intent was to create various versions of the song with different instrumentation in the repeated sections, to help Maura really understand, through listening, that each section repeats. Also, I think she's listened to the music so much that she tunes it out, and using different instrumentation (or even dropping measures or notes) can, I think, make the song fresh and encourage closer listening.

It took me a little experimentation to work with the Noteflight app, but it wasn't too hard, and the help section is very good.

It was easy to get the program to export .WAV files that I could then burn to CD.  In fact, I created audio files with a lot more variations than the four scores just by changing the instrumentation and exporting a .WAV file with the new instrumentation.  You can hear MP3s of a couple of audio files I created from the Noteflight scores here:

Guitar + accompaniment + flute (A1, B1) + clarinet (A2, B2) (this is from the last score above)
Guitar + Alto Sax (A1, B1) + flute (A2, B2), no accompaniment (generated from the second score listed above)

I could imagine this being useful in a lot of ways. To take just the simplest example, you could easily generate audio files of any song, at any arbitrary tempo, for a student to play along with. Or you could transpose a simple song to a different key to help a student practice sight reading. Or you could add dynamic contrast different from, or more noticeable than, what is found on the CDs.

In any event, I thought it was worth passing along. You might also let parents know about it. I think that parents (like me) whose musical interest and knowledge outstrips their ability to play the guitar might appreciate it.

Best,
