BrassTune is a focused practice companion for brass players. It brings the tools for intonation, timing, warm-ups, scales, score work, class progress, and personal review into one clear routine. LIVE BRASS TUNER See the detected written note, octave, cents, frequency, confidence, and whether you are flat, centered, or sharp. BrassTune shows estimating, unavailable, interrupted, and denied states honestly instead of inventing a reading. PRACTICE TOOLS - Run guided warm-ups and visual routines. - Practice major, natural minor, harmonic minor, melodic minor, and chromatic scales. - Choose one, two, or three octaves when the range fits the selected instrument. - Use a configurable metronome for tempo, meter, subdivisions, accents, count-in, sound, and haptics. - Play reference tones, drones, and intervals. SCORE PRACTICE Import a PDF or photo from Files or Photos, review each page, add focus measures and passage notes, set a target tempo, and start a manual guided all-notes routine. Score files stay on the device unless you explicitly export or share them. CLASSES FOR STUDIOS AND ENSEMBLES Join multiple classes by code or invitation. Students see their own aggregate practice progress and control whether timing and pitch summaries are shared. Class owners can review aggregate minutes, sessions, tuning trends, and activity signals; assistants receive a private read-only view. Recordings, reflections, scores, and individual session detail are never exposed through Classes. PROGRESS YOU CAN TRUST Review saved sessions, reflections, practice totals, pitch summaries, and completed routines. Guest practice works without an account. Optional account and class features are clearly separated from local practice. PRIVACY-FIRST AUDIO The microphone runs only when you start a listening feature. Native recordings stay on the device unless you explicitly export or share them. BrassTune does not use advertising trackers. BrassTune supports trumpet, cornet, flugelhorn, horn, trombone, bass trombone, euphonium, baritone, and tuba profiles with written-pitch and transposition-aware feedback. CREATED BY Kelvin Guo and Arya Salem.
