I’m guessing that only 6th & 7th Graders are in the band and maybe 5th Graders. And it must count as PE or Physical Education because those green & blue uniforms are their PE uniforms, while the two boys in white shirts and black pants are in their school or classroom uniform.
It is almost all drums in all the bands here, this one with cymbals and some kind of scrappy rhythm instrument on the back row. I’m guessing again that is because of lack of money for instruments and music teachers or a priorities thing. The high school bands usually have a few girls playing xylophone with some bigger cities adding brass and reed instruments, but not many.
The group above is practicing in the city sports park across the street from the Primary School, Escuela Central. And I suspect they are getting ready for the September 15 Independence Day Parade and subsequently the December Christmas Parade. I admire the few girls who play drums which the boys tend to dominate here (and maybe everywhere).
Life in a small farming town in Costa Rica! ¡Pura Vida!
