Built by a trumpet player, for trumpet players.

Play into your microphone and watch the needle respond live, with a staff view that highlights the closest note as you play.
Listen to a note, try it yourself, and let the app tell you if you're spot on, a little sharp, a little flat, or playing a different note entirely.
Switch between gold and silver valve finishes, choose from five built-in soundfonts, or import your own custom SF2 file.
Do-Re-Mi, C-D-E, or German-style H for B — Trumpet Keys adapts to how you read music and your Mac's language.
Every note accounts for proper Bb trumpet transposition — including tricky enharmonic fingerings that actually differ.
From picking a note to playing it back — here's what practicing looks like.
