Completed in February 2010, this work was created by Takashi Suzuki, who presides over the amateur concert group Lark Trombone Quartet, and premiered at the 10th Mori-no-Hall Hashimoto Ensemble Concert on November 20, 2010.

The title is a coined word without specific meaning, but think of it as "the world of trombone" or "thinking of trombone". Divided into three parts, fast-slow-fast, it starts with a light rhythm, changes the feel to Andante, and then returns to a light tempo.

This is a trombone quartet, but you can substitute tuba for bass Trombone. However, it requires a good balance of sound and volume, so pay particular attention to that as well as the intonation and timing of bell tones.
