Augmented-Major Seventh Chord
An augmented triad with an added major seventh interval, creating an uplifting, ethereal, and harmonically ambiguous sonority that appears in impressionist music, jazz reharmonization, and film scores—combining augmented's symmetry with major seventh's shimmer.

I. Conceptual Positioning
🎯Problem Solved
How to create upward-pulling harmony with bright, floating character—the augmented-major seventh provides coloristic alternatives to standard tonic and dominant functions, enabling smooth voice leading via chromatic contrary motion and creating the 'levitating' sound of impressionist and film music.
🔨Skills Built
- •Construct augmented-major seventh chords in all keys
- •Apply +maj7 for coloristic reharmonization
- •Understand the dual upward pull (augmented fifth + major seventh)
- •Use +maj7 in impressionist and film contexts
- •Exploit chromatic voice leading possibilities
