Tunes in our "Sounds" series introduce various sounds or bits of melodies one at a time or in groups, building to a certain point, then un-building back to the base. Whacky Sounds uses the building and unbuilding technique by combining voices and Boomwhackers® (C scale tubes).
The form used in the recording is indicated at the bottom of the music. Use it as is, or alter the form to suit your own situation. If you do not wish to use the recording, you can vary the length of the piece as well. (from Music K-8, Vol. 10, No. 5)
