Several weekends ago, I found a few peaceful moments to play tunes while my son (5) was building fantastic structures. The result, my first original tune for melodeon, "Nikolas Builds." It's played on a three-row G/C/F accordion (on the C/F rows -- easily played a whole step higher on a D/G melodeon). The B part makes extensive use of the "accidentals" button on the inside row (in both directions) -- in a sense, the tune is a study in using that oft-neglected button! In any case, I have become much more fluent in using that button since this recording, and I now play the tune at a faster clip -- I'll post a newer recording when I get the chance.
For now, here is the early, slow version of "Nikolas Builds," copyright 2012.
