"The next piece needs to be all about the arpeggios and big taiko drum action."
Grok:
"Kumi" (組) is Japanese for a group or team. In "kumi-daiko", it means an ensemble of several taiko players drumming together, as opposed to one drummer alone. The same word as a verb, "kumu", means to put together or braid. That's why I liked it for this piece: the drums and the arpeggios get woven together into one rhythm.
