Trumpet Keys is your practice companion for Bb trumpet — built by a trumpet player, for trumpet players.
Select any note and instantly see its correct valve position, its place on the staff, and hear how it should sound. Then flip it around: play the note yourself, and let the built-in tuner listen through your microphone to tell you if you nailed it.
WHAT YOU GET
- Note Identifier
Choose any note — natural, sharp, or flat — across the full practical range of a Bb trumpet. See the exact valves to press, animated in real time, plus its position on a proper musical staff.
- Real-Time Tuner
Play into your microphone and watch the needle respond live. A built-in staff view highlights the closest note as you play, so you always know exactly where you stand.
- Smart Practice Mode
Pick a note, listen to it play, then try it yourself. The app listens back and tells you if you're spot on, a little sharp, a little flat, or playing a different note entirely.
- Make It Yours
Switch between gold and silver valve finishes, choose from five built-in trumpet soundfonts, or import your own SF2 soundfont file for a completely custom sound.
- Multiple Notation Systems
Comfortable with Do-Re-Mi? Prefer C-D-E? Or German-style H for B? Trumpet Keys adapts to how you read music, and automatically matches your Mac's language.
- Correct Bb Transposition
Every note accounts for proper Bb trumpet transposition, so what you see and hear always matches what a real trumpet player expects — including tricky enharmonic fingerings that actually differ (yes, C# and Db aren't always the same valve).
WHO IT'S FOR
Whether you're a beginner learning your first scale, a student building muscle memory, or an experienced player just double-checking an unfamiliar fingering, Trumpet Keys gives you a fast, visual, and interactive way to connect notes, valves, and sound.
No ads. No account required. No internet connection needed — just you, your trumpet, and your Mac.
Practice smarter, not louder.
