Thunderbirdexhibits all the elements I love about the flute: its lively and sprightly nature and its ability to conquer quick rhythmic ideas and long lyrical lines gracefully. The lively rhythmic movement and ensemble diversity are mirrored in an ABA form, with a gentler, lyrical middle section. The piece was written for the Harmony Project Phoenix and was named by the elementary-age soloists who played on the original recording.
