Trombone Trainer

About

Trombone Trainer turns slide practice into a game. Pick an exercise, hit play, and move to the correct slide position as each note sounds — the app scores you in real time and highlights the note you're on, so you build the link between what you see on the staff, what you hear, and where your slide goes. Built for trombonists: • Learn the seven positions — the on-screen guide shows the right slide position for every note, and real-time scoring gives you credit for holding it as the note plays, with a clean-run detector that rewards mistake-free passes. • Bass-clef staff — everything is written and read in bass clef, the way trombone music actually looks. • Play-along loops — eight measures on the staff, played back with a piano-style chord under each measure, so you train positions in a musical context, not in silence. • Alternate positions — set your own preferred slide position for notes that can be played in more than one place. • Swipe to control — swipe left/right to change tempo. • Built-in libraries — major and minor scales, chromatics, arpeggios, technical studies, and more. • Track your progress — daily/weekly/monthly trends, streaks, per-song stats, and unlockable badges. Read music your way: • Note names in letters (C D E), German (H / B), or fixed-do solfège (Do Re Mi) — switch independently of the app language. • Available in English, Spanish, French, German, Portuguese, Italian, and Japanese. Free to start: • The free version includes scale libraries to practice positions right away. • Upgrade to Standard to unlock every song, import songs and libraries, and share songs; Pro adds creating, deleting, and exporting whole libraries. Both are one-time purchases — no subscription. Whether you're a beginner learning where the positions are or an advancing player pushing tempo, Trombone Trainer keeps the reps focused, musical, and measurable.
