iPhone
New: import videos straight from the Photos app. Chordwerk uses the audio track and shows you chords, key and scales to play along.
Practice guitar with the songs you actually want to play.
Import a song or record it – Chordwerk detects chords, key, tempo and song sections right on your iPhone. Then just play along: the app shows you in time which chord is sounding, how to fret it and which notes on the fretboard fit a solo.
PLAY ALONG WITH CHORDS
• Automatic chord detection for the whole song
• Current and next chord in large type, upcoming chords always in view
• Chord diagrams for every chord – also for Eb tuning and Drop D
• Playback speed 50–100 % without changing the pitch
• Sharps or flats – however you read music
SCALES & IMPROVISATION
• Fretboard with the key's pentatonic scale and the notes of the current chord
• Show intervals (1 3 5) or note names
• Zoom and full-screen landscape view of the whole fretboard
FOCUSED PRACTICE
• Chordwerk detects the song sections – practice one section or several in a row
• Loop, slower tempo, metronome and count-in
YOUR SONGS
• Import audio files: MP3, M4A, WAV, AIFF, FLAC and more
• Import videos – from Files or straight from the Photos app; Chordwerk only uses the audio track
• Record yourself: your own playing or a song through a speaker
PRIVATE
All analysis runs on your device. No sign-up, no tracking, no ads – your songs never leave your iPhone.
