I like the concept behind pulsaria or harmondia but It sticks out too much. I like the sound of resovia or vibralia because it sounds foreign or exotic

those names have a more natural, organic feel while still maintaining that sense of mystery. They don't immediately scream "this is about music" but still carry those subtle resonances. What if we played with some variations on that style? Like:

Sonovia (from 'sonic' but disguised) Rytharia (rhythm, but more exotic) Cantoria (from 'cantare'/singing, but feels like a place)

Or we could go even more subtle with something like "Aethria" or "Revania" where the musical connection is even more understated?
