Music Theory Workbench
Explore scales, chords, intervals, keys and tempo in one visual workspace with instant local audio playback.
What Is the Music Theory Workbench?
The Music Theory Workbench combines scales, chord construction, interval analysis, key inspection and tap tempo. Notes appear on an interactive piano and in formula form, diatonic harmony is calculated from the selected key, and scales, intervals and chords can be played through the browser’s local audio engine. Nothing is recorded or uploaded.
How It Works
Choose a root note and open Scales, Chords, Intervals, Tempo, or Key & Harmony. Select a scale or mode to see its notes and formula, construct triads and extended chords, compare two pitches by interval, tap a beat to estimate tempo, or inspect a key signature and its diatonic chords. Use the playback controls to hear the result and move directly into the Circle Of Fifths or Chord Progression Studio when you want to compose with it.
When to Use It
Use it while learning harmony, checking a song key, finding chord tones, teaching a lesson, transposing an idea, programming MIDI, or validating a progression before recording.
Frequently Asked Questions
- Does the workbench play sound?
- Yes. It synthesizes short reference tones with the Web Audio API after you press a playback control. Audio stays entirely on your device.
- Which scales and chords are included?
- The workbench includes major, natural, harmonic and melodic minor plus the diatonic modes, along with common triads, suspended chords, sixths and seventh chords.
- Is this a tuner or microphone analyzer?
- No. It is a theory and reference workspace and does not access the microphone. Use an instrument tuner for intonation and pitch detection.
