ChordSequence review
A free chord toolkit for lookup, progression creation, playback, charts, and exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ChordSequence is a free browser-based music toolkit for songwriters, producers, students, and musicians. It brings chord progression generation, chord lookup, transposition, playback, song charts, and chord-sheet creation into a modern web browser without installation. Chords can be looked up by name or entered notes for guitar, piano, and ukulele, while generated progressions can use genre-based examples and play with piano, guitar, bass, and drum sounds. An Android Chord Player app extends the toolkit with offline progression editing and playback.
For composition and practice, the feature set covers several useful stages of a song workflow. Users can transpose progressions by key or semitone, create chord sheets with lyrics and chord placement, and build song charts with synchronized chord playback and printing. Progressions can be exported as MIDI or WAV, and the Android app adds M4A export alongside MIDI and WAV. That combination makes ChordSequence suitable for exploring harmony, preparing printable charts, and moving progression ideas into other music workflows.
The vendor describes ChordSequence as entirely free, with no paid plans presented. Its platform coverage is straightforward: browser access for the main toolkit and Android for offline mobile playback and editing. Choose it if you want free chord lookup, progression generation, playback, transposition, chart creation, and export tools in one service. Consider another option if you need a mobile app for a platform other than Android or chord lookup centered on instruments beyond guitar, piano, and ukulele.
