ChordSequence

Chord Sequence is a free browser-based tool for building, playing, and exporting chord progressions. Drag chords onto a timeline, choose a rhythm style, and hear the progression played back live with piano, guitar, and bass — no DAW, plugin, or installation needed.

Key features:

• Drag-and-drop chord editor with 37+ chord qualities (major, minor, 7ths, 9ths, sus, add, altered, and more)
• 17 rhythm styles (pop, rock, jazz, reggae, hip-hop, Latin, worship, and more), each with its own instrument arrangement
• Live playback with adjustable BPM, metronome, and instrument mute/solo
• One-click transposition to any key
• Export progressions to WAV, MP3, or MIDI for use in any DAW
• Import/export via MIDI hardware or file
• Save and revisit songs without creating an account
• Fully responsive — works on desktop, tablet, and mobile browsers

Chord Sequence also includes a bass tab editor and player as a separate tool for working out bass lines note by note.

No installation, no subscription, and no account required to use the editor.
