Abstract
Abstract A percussion type musical instrument is formed as a representation of a flower having radiating petals. Each petal consists of an open bottom echo chamber and an elliptical tone bar secured to the top of the chamber by snap-type fastening means formed integrally with the chamber. The chambers are integrally formed with a hub section mounted to a downwardly extending stem-like post. Another hub section or cap is snapconnected to the first hub section and frictionally engages the upper end of the post to prevent rotation of the echo chambers about the post.
