About
JazzValve is built specifically for jazz trumpet. It combines B♭ fingerings, jazz scales, triads, hard-bop licks, and ii–V–I practice in one minimal app. Unlike generic fingering tools, it teaches the actual language of jazz and how to use it musically.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
