Seven valve combinations × the harmonic series — every note the horn can play, drawn as a grid you can fly through.
Read the chart like a trumpeter: each column is a valve combination — shown as its fingering glyph — and each row is a harmonic. Tap a note to hear it, see it on the staff, and watch every other fingering for that pitch light up.
