Teach rhythm better!
Demonstrate hard-to-understand rhythms by placing marbles (or similar) in notches relating the location of individual notes to the beat. Note that wood color may vary and 16 optional marbles are randomly selected. Instead of marbles, you can also use wooden beads, candy (Skittles, M&Ms), or gum balls. Correlates to lessons in the Creative Chords keyboard improvisation series.
