The Harmonic Architect

This unit focuses on vertical harmony, teaching students how to build, identify, and invert triads and seventh chords, which are the primary harmonic units in Western music. The Harmonic Architect turns that idea into something you can manipulate directly and watch respond.

This unit focuses on vertical harmony, teaching students how to build, identify, and invert triads and seventh chords, which are the primary harmonic units in Western music. It focuses on Triad Qualities (Major, Minor, Diminished, Augmented), Seventh Chord Qualities, Inversions and Figured Bass, Roman Numeral Analysis, Chord Voicing and Spacing from the “Unit 3: Music Fundamentals III: Triads and Seventh Chords” section.

You can drag elements directly on the canvas; the “STRUM CHORD”, “+ ADD 7th” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.

You'll build intuition for Triad Qualities (Major, Minor, Diminished, Augmented), Seventh Chord Qualities, Inversions and Figured Bass, Roman Numeral Analysis, Chord Voicing and Spacing — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Music Theory alone.
