CircleCraft: Circle of Fifths

Stop memorising chords. Start understanding why they work together.

CircleCraft is an interactive Circle of Fifths and guitar music theory app designed for guitarists, songwriters, music students and musicians who want to understand harmony, discover chord relationships and build better chord progressions.

SEE HARMONY WITH THE CIRCLE OF FIFTHS

Explore an interactive Circle of Fifths and discover how musical keys, scales and chords relate to one another.

Choose a key to explore its diatonic chords and harmonic relationships. Colour-coded chord functions and Roman numerals help you understand the role each chord plays, making music theory easier to see and apply.

BUILD CHORD PROGRESSIONS

Create music with CircleCraft's interactive Chord Progression Builder.

Build chord progressions, explore common chord patterns, experiment with harmonic movement and discover which chord could come next.

See how your selected chords relate to the Circle of Fifths and develop a better understanding of chord progression theory while creating your own musical ideas.

HEAR YOUR CHORD PROGRESSIONS

Turn music theory into something you can hear.

Play back your chord progressions and listen to how chords sound together. Explore harmonic movement, compare different progressions and connect visual chord relationships with the music they produce.

UNDERSTAND CHORD RELATIONSHIPS

Go beyond memorising guitar chords.

Analyse chord progressions to explore harmonic function, chord relationships, voice leading and cadences.

Learn why certain chords work well together and how harmonic movement creates musical direction and resolution.

EXPORT CHORD PROGRESSIONS TO MIDI

Take your musical ideas beyond CircleCraft.

Export your chord progressions as MIDI files for use in compatible digital audio workstations (DAWs), MIDI editors and music production software.

Build your progression, listen to it and export it for further development in your own compositions.

EXPLORE MAJOR AND MINOR HARMONY

Discover more than just major keys.

Explore major and minor harmony, including harmonic minor, melodic minor and seventh chords.

Use the Circle of Fifths to investigate chord functions and harmonic relationships across different keys and minor-scale variations.

LEARN MUSIC THEORY AND TRAIN YOUR EAR

Develop your understanding through interactive learning and practice.

Use music theory guidance, Practice mode and Ear Training to reinforce your knowledge of chord relationships and harmonic functions.

Connect what you see on the Circle of Fifths with what you hear in music.
