I wrote a little round last weekend, with the holiday season and new year in mind.
It was fun to work on, in a crossword-puzzly kind of way. ("Who sings which note in each triad, and when?")
Here's a chart of the melody and a test run I recorded on my Tascam 8-track.
Once through in unison, then twice through for each of the three round parts.
Ready? Here we go!
