This One Time…At Band Camp…
I attended a number of summer music programs as a kid. Not sure if I picked up this fun musical round at Kinhaven, DARTS, SYMS, or elsewhere. But it stuck with me, and has been a source of fun for years, sharing an earworm that helps kids (and adults) remember their musical intervals.
As I couldn’t find any other copy or reference to it online, I decide to typeset it so future generations of music teachers and kids could enjoy!
