The Advanced Music Theory Web App

Explore nine fully developed areas: Figured Bass, Chromatic Harmony, Chord Progression Maps, Non-Harmony Notes, Suspensions, Modulation, Four-Part Writing, Melodic Composition and Jazz Theory. Every topic combines clear teaching with professionally engraved notation, realistic sampled-piano playback and practical activities that turn complex theory into something you can see, hear and control.

Build and realise figured bass, investigate inversions, create correctly voiced SATB harmony and receive detailed feedback on spacing, doubling, tendency tones, parallels and voice leading. Explore secondary dominants, Neapolitan chords, augmented-sixth chords, pivot-chord modulation and major and minor progression maps. Learn to recognise and construct passing notes, auxiliaries, appoggiaturas, suspensions, retardations and decorated resolutions.

Develop complete eight-bar melodies and four-part exercises using interactive notation, rhythm controls, playback, tempo adjustment, analysis and PNG export. The Jazz Theory area lets you build extended chords, compare rooted and rootless voicings, explore chord families and hear authentic practical voicings.

The app also includes quizzes, answer checking, reveal tools, alternative valid voicings, a searchable glossary, a detailed User Guide, random lesson exploration and customisable display and audio options. The app is designed to bring advanced theory to life with an experience that is rigorous, musical and genuinely enjoyable.

Learn faster. Teach more effectively. Hear the theory—and make it your own.
