Zapatitos builds out of the traditional taps from the anchor bass that most marching units use to stay in time (when they aren’t playing music or drumline cadences), and it also uses this idea as a musical motif to build up to the reprise of the main groove at the end. A simple walking bass line is coloured with texture from the snare drum before a lyrical melodic line is introduced by the tenors, and then more or less the same thing happens again. Nice mix of highs and lows here, and it should be plenty of fun without too much commitment of rehearsal time.
