The Color Tree vs Rehearsio

Take any set of notes that sit side by side on the circle of fifths. Collect every one of those sets, and they self-organize into a 12-row object - 67 sounds, arranged from simple to complex and from dark to bright. That's The Color Tree, discovered by Andrew Sheron in 2021. Many common scales and chords you already know appear here, along with many you might not recognize. Tap any sound to hear it and visualize it. Key Features: • Completely free - no ads, no account • Listen - customizable playback for every sound on the object • Scale visualizer - see the notes laid out on your instrument of choice • Fully offline - no connection required • Deep links to The Color Encyclopedia - jump to the full entry for any sound For composers, improvisers, music theorists, and anyone else with curious ears. The Color Tree maps the 12 special cases. The Color Encyclopedia contains the entire space - all 351 families of notes in twelve-tone music.

Everything you need for a practice session, in one app. Sheet music, annotations, metronome, tuner, recorder, notes and practice history — all inside one rehearsal session. No switching between apps. No writing the same thing down twice. You start practicing, and everything you need is already there. When you finish, Rehearsio leaves you with a record of what you actually worked on. WHAT A SESSION LOOKS LIKE Start a session and the clock runs automatically. Your score is open, the metronome is a tap away, the recorder is ready, and your practice time is tracked by piece — not just as one total. When you finish, your session summary shows what you practiced, for how long, and what you recorded. SHEET MUSIC YOU CAN WRITE ON Import PDFs from Files, Mail, or anywhere you can share. Add fingerings, bowings, breaths, reminders and more directly to the page. Six pencils and a highlighter, musical stamps, typed notes, eraser and undo — everything is there when you need it. Your annotations stay with the score, even when you make them in the middle of a run-through. Share an annotated copy with your teacher while keeping the original untouched. A METRONOME THAT HOLDS THE BEAT Set time signatures, accents, subdivisions and tempo, or tap in the tempo yourself. It keeps playing while you use the rest of the app — even when you turn the page. A TUNER FOR ANYTHING WITH A PITCH A clear note, cents display and stable needle. Choose your instrument for more focused tuning, or use chromatic mode for anything. A reference note is also available when you prefer to tune by ear. RECORD THE RUN-THROUGH Record without leaving the score. Start a take, keep practicing, and listen back afterwards — with the annotations you made during the session still there. Recordings stay on your device unless you choose to share them. NOTES AND TASKS THAT KNOW THE PIECE What your teacher said. What to fix before Friday. What to ask next lesson. Keep notes and tasks attached to the piece so they are there when you need them again. SEE THE WEEKS ADD UP Track practice days, minutes per piece, tempo and progress over time. Rehearsio counts what you actually played, giving you a clear picture of your practice — not just what you intended to practice. BUILT FOR THE MUSIC STAND Large controls, warm paper-coloured surfaces and a distraction-free interface designed to be read while you play. Rehearsio supports VoiceOver and TalkBack so every control is clearly identified. YOUR WORK STAYS YOURS No account. No sign-in. Nothing is uploaded. Your scores, annotations, notes, recordings and practice history stay on your device. You can export your entire library to a single file and keep your own backup wherever you choose. FREE. NO ADS. Rehearsio is free to use, with no advertising and nothing to buy inside the app. Rehearsio is made by one person who practises. If something is broken or missing, you can reach them directly through the app.
