Music Theory Companion is designed for exploring scales, chords, and harmonic relationships when studying music, composing, songwriting, or tuning an instrument. Its reference material and practice tools bring theory topics and hands-on exercises together in one app.
When you need to explore scales and modes
The app provides a library of 86 scales and modes for examining different melodic possibilities. This can support songwriting, composition, or instrument tuning by giving you a range of scale structures to consult while working on music.
When a melody needs harmonic alternatives
Music Theory Companion helps you investigate relationships between scales and chords. You can look for alternate chords to harmonize a melody or consider different scales for developing a song, making the connection between melodic material and possible harmony easier to examine.
When you want to study tonal relationships visually
The circle of fifths is available for each scale, with views that can be followed in both clockwise and anticlockwise directions. This gives you a visual way to examine nearby key and harmonic relationships through the circle of fifths or fourths.
When you are working on voice leading and modulation
The Cube Dance guide presents voice-leading ideas based on Neo-Riemannian theory. It includes smooth chord progression options for exploring voice leading, chord movement, and modulation during composition or theory study.
When you need chord references and practice controls
A library of more than 1,000 chords includes chord construction material for guitar and piano. For practical study, the pitch detector can be used while practicing scales, while the metronome helps you maintain a selected tempo during exercises.
When you want to connect with other musicians
The app also provides access to a Music Theory Companion community on Facebook. The community is intended for connecting with other musicians, sharing music, and providing feedback alongside discussion of chord progressions and music theory.
