Accompanist: Music Speed

Accompanist is a real-time music slow downer and speed changer. Take any song you own and pull the tempo down to learn it — or push it up to performance speed — with the pitch locked to the original key. Built for dancers and teachers, and for any musician learning a song by ear. All in real time, all on your device.

CHANGE SPEED ANY WAY YOU LIKE • Speed and volume bars always on screen — drag either as the music plays. • A clear 1× marker to snap back to the original. • Plus / minus buttons that nudge by 0.01×. • A type-in field for an exact speed. • Quick presets across your range. • Set your own range and centre — from a gentle 0.9–1.1× to a wide 0.25–3×.

KEEP THE PITCH — OR LET IT MOVE One toggle decides how the music responds: • ON — tempo changes, pitch stays in the original key. Perfect for drilling choreography slowly, or learning a riff note for note. • OFF — the classic record-speed effect. Set the speed back to exactly 1× and the song returns to its original sound.

SEE THE WHOLE SONG AT A GLANCE A tempo chart maps every speed and volume change across the song, above a waveform of the music — with your loop and markers on it. Drag it to scrub and read values anywhere.

LOOP & DRILL A TRICKY SECTION • Mark A and B and the music loops that section on repeat — drill a hard 8-count, or a fast solo, as slow as you like. • The loop region shows right on the progress bar, and clears with one tap. • Speed Trainer — each time the loop comes round the tempo nudges up, so you build to full speed automatically.

KEEP THE BEAT • Tap along to set the BPM, then get a "5, 6, 7, 8" count-in before the music starts. • Turn on the metronome to click along at your tempo while you teach. • Drop section markers (Intro, Chorus, the lift) and jump straight to any part of a song.

A PROFILE FOR EVERY DANCER (PRO) • Record your speed and volume changes as a song plays and save them under a dancer's name. • Press play and the app drives speed and volume for you — hands-free — so you can watch the floor. • Edit the whole routine point by point in the profile editor. • Share a profile with another dancer; it reattaches to the same song on their device. • Profiles back up to iCloud and restore on your other devices.

VOLUME, FADES, AND BOOST • Per-song volume, independent of your phone's volume. • Boost above 100% to lift a quiet recording; set your own volume range. • Smooth fade-in and fade-out.

EXPORT YOUR ADJUSTED SONG (PRO) Save the music at your chosen speed — following your profile's changing speed and volume — as an audio file. Pick the format, see the size, then play it anywhere.

ORGANIZE INTO FOLDERS • Add a whole folder and keep its subfolder structure — perfect for a class (Warm Up / Barre / Centre). • Make your own folders, open them, and play straight through a folder. • With Accompanist Pro, sync folders across iPhone and iPad over iCloud. • Share a whole folder — songs and profiles included — with another teacher (Pro) via a link. • Import from Files, or from Google Drive / Dropbox via Share ▸ Accompanist. • Pull the audio out of a video (Pro). • Keep playing in the background and over AirPlay.
