Feature Comparison
Interactive Circle of Fifths
Dynamic Circle & Inner Ring Scales
The central interactive circle is just the start. Tap on any key to instantly reconfigure the entire app's context. The innovative inner ring gives you one-tap access to essential scales beyond the standard major and minor, including the Pentatonic, Blues, Diatonic, and Diminished scales. This allows for deep, on-the-fly exploration of different musical colors and moods directly from your chosen root note, making scale theory practical and immediate.
Integrated Piano & Guitar Visualizers
Theory becomes tactile with our responsive instrument visualizers. Select any chord or scale, and the app immediately displays the correct notes and optimal fingerings on a clean, playable piano keyboard and guitar fretboard. This feature bridges the gap between knowing a chord symbol and physically playing it, accelerating your ability to apply theoretical knowledge to your instrument during practice or songwriting sessions.
Harmonized Scale & Chord Function Panel
Understand music at a deeper level. For any selected key, the app clearly displays the full harmonized scale (e.g., C, Dm, Em, F, G, Am, B°) alongside its Roman numeral analysis (I, ii, iii, IV, V, vi, vii°). Each chord is tagged with its scale degree and its common resolution path ("Resolves To"), teaching you the functional harmony that drives compelling chord progressions in a clear, visual format.
Interactive Chord Sequencer
Turn knowledge into music. Use the Chord Sequencer panel to build and audition chord progressions in real-time. Drag and drop chords from the harmonized scale to create a sequence, then play it back to hear how the chords flow together. This hands-on tool is perfect for experimenting with song structures, understanding cadences, and finding inspiration for your next composition directly within the app.
