Commissioned by Saitama Teions Club.
Although scored as a sextet, parts can be doubled to form a bari-tuba orchestra. In fact, that setting was used in the premiere.
The baritone solo in two movements can also be played on euphonium (euphonium parts are included). Also, the 4th euphonium can be played on Eb Tuba, but please be careful to match tone color. It's not so difficult technically. Overall balance is key for success considering the amount of parts.
