Program notes:
Commissioned by Takanawadai High School Band, 2021. The title refers to "richness". The theme is "musical and technical abundance of expressiveness". While composing, I envisioned a bright and glorious divertimento-like piece.

Performance notes:
The cadenza in the middle part can be played freely; if players have challenges with tonguing such as for clarinets, play with slurs. In the fast part of the second half, a 16/16 time-like rhythm appears in 4/4. Work out the length of the chords and other notes and how the rhythm meshes with them.
