This is an instrumental performance piece that offers an opportunity for several groups of students to play together. Each of the instruments is optional, however, except the recorder, which has the melody. So you can add or remove as many instruments as you want. The kit includes extracted parts for Boomwhackers®/Mallets, Percussion, Ukulele/Guitar, and Recorder (D,E,G,A). (from Music K-8, Vol. 23, No. 4)
