Alegria is an education piece for children of primary school age. It focuses on aspects of rhythm and ostinato, and it is based on the flamenco principle of 3+3+2+2+2 (12 beat cycle). Flamenco music is based on Spanish gypsy music, and is often accompanied by clapping, so there are clapping parts included for members of the orchestra. The audience may learn the simple clapping patterns (on the next page), so they can accompany the orchestra when they hear the patterns. The central section in 5/8 is intended as an asymmetrical contrast to the duple and triple meters of the outer sections. “Alegria” means “joy” or “happiness” in Spanish.
