Scale harmonization is the process of building chords from each degree of a scale by stacking thirds. Each note of the scale becomes the root of a chord, producing a set of diatonic chords (triads and seventh chords) that naturally belong to that key.

What is Practice Mode in the Scale Harmonizer?

Practice Mode is an interactive study tool that cycles through all diatonic chords with a synchronized fretboard visualization (switch between scale and arpeggio view), adjustable tempo (40–240 BPM), and audio playback. It includes ii-V-I progressions and secondary dominant exercises — the fretboard automatically shows the contextually correct scale for each chord (e.g., Dorian for the ii, Mixolydian for the V7).

Degree-by-Degree Analysis

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