Music Tools: Chord Detector

Hear a song. Find its chords. Make it your next practice session.

Music Tools turns your own audio recordings and imported files into a chord chart you can play along with. Record with the microphone, import from Files or share a recording from Voice Memos. Analysis runs on your iPhone, without an account or a cloud upload.

FIND THE CHORDS • Detect chord changes, estimate the musical key and tempo. • Follow the chord timeline while the recording plays. • Check confidence indicators and correct a chord when the estimate needs help. • Try the included demo before allowing microphone access.

MAKE IT PLAYABLE • Transpose a chart into a more comfortable key. • Try capo positions or simplify chords for practice. • Tap a chord for guitar, ukulele or piano diagrams. • Slow playback and loop a difficult passage. • Keep recordings and analyses together in your personal songbook.

EVERYDAY MUSIC TOOLS • Tune your instrument with the chromatic tuner and alternate tunings. • Keep time with the metronome. • Explore live chord recognition through the microphone. • View estimated melody notes and recognize words on device when a supported speech language is installed.

YOUR AUDIO STAYS WITH YOU No sign-up, advertising or tracking. Recording, chord analysis and speech recognition take place on your device. Saved songs are stored locally. You choose what to share or export.

Recognition is an estimate: instrumentation, background noise and complex arrangements can affect results. Clear recordings of guitar or piano are a good starting point. Melody and lyric recognition may need correction; installed language support is required for speech recognition. The app does not download or decrypt protected music streams. Import only audio you have the right to use.

Interface language: English.
