Rhythmic patterns are created based on a specific time signature and are made up of combinations of notes and rests. They can show either even or uneven rhythms depending on whether the pattern has a steady beat or combines long and short sounds. The module teaches students how to create rhythmic patterns in 2/4 and 3/4 time signatures by identifying the time value of different notes and rests and arranging them into measures that fit the time signature. Students are asked to clap, tap, and chant rhythmic patterns as well as create their own patterns based on songs.
