ChordBook — Songwriting Studio

Intro

What is ChordBook?

A browser-based songwriting studio for building chord progressions and rhythm patterns.

Build your song structure

Start with an Intro and add Verse, Pre-Chorus, Chorus, Bridge, and Outro sections in any order. Each section is an independent block with its own chord table and short notes.

Chord progressions

Pick a key and mode, then fill the bar-by-beat chord tables. Use the built-in diatonic chord palette, type your own chords, or generate progressions from classic Roman numerals with the Inspire controls.

Bridge strategies

Need a contrasting section? Choose from harmonic strategies like Relative Minor, Line Clichés, and Modal Borrowing to create bridges that resolve back into the Chorus.

Tempo and rhythm

Set BPM and time signature, then use the synced metronome to keep time. The drum machine gives you a 16-step sequencer with kick, snare, hi-hat, and open hi-hat, plus the option to load your own samples.

Save and export

Save your work as presets, export your full song as a text file, and come back later — the drum pattern travels with the chord sequence.
