Commissioned and premiered by brass ensemble "Brass Collection". All members are from Toyama Prefecture, Japan.Trumpet Hirofumi Yamauchi said "Feel free to write anything you would like!" I decided to write a rhythmic and lively composition in three-part form. The first section is based on an eighth-note rhythm pattern with an upbeat feel. The middle section is a chorale made from five notes F?G?Bb?C?Eb. Gauge the atmosphere of the audience and the hall and produce a resonant sound. The last section involves a driving 16th-note rhythm.
