We begin by experiencing cyclical rhythms in the context of different pieces of music. In these videos, every beat is counted aloud. The number after the video’s title corresponds to the number of beats in each measure. When you press play, a measure-for-nothing is counted: simply listen to it and get ready to count and clap. After the measure-for-nothing, the music begins: count aloud and clap along, synchronizing your voice and movements to the beat.
