Degree-by-Degree Analysis
The I chord (A# major) is the tonic — the gravitational center of the key. The ii chord (C minor) is the minor subdominant, commonly used to approach the V chord. The iii chord (D diminished) functions as a substitute for the I or vi. The IV chord (D# unknown) is the subdominant — it adds motion and moderate tension. The V chord (F unknown) is the dominant — it creates the strongest tension that wants to resolve to the I. The vi chord (A minor seventh) is the relative minor — it brings emotional color and depth. The vii° chord (A# unknown) is the diminished — the most tense, rarely used alone, usually leading to the I.

How to Use This Scale
Use over dominant 7th chords. The added passing tone ensures that the root, 3rd, 5th, and b7 fall on downbeats during eighth-note runs — the 'trick' that makes bebop sound professional.
