Harmonic Function

The F♯ major sixth chord commonly functions as the tritone substitution in C major or tonic in F♯ major. Its harmonic role varies by key — in major keys it provides stable harmonic grounding.

The major sixth chord adds a major sixth to the major triad. It has a warm, pleasant quality with a hint of jazz sophistication, often used as a substitute for the plain major chord. The F♯ Major Sixth Chord specifically contains 4 notes: F♯, A♯, C♯, D♯ (formula: 1-3-5-6). On piano, F#-rooted chords place the root on a black key, creating hand positions that many pianists find ergonomically comfortable for fast passages. Progressive rock, jazz fusion, and electronic music use F#-rooted chords to create unexpected harmonic shifts and chromatic modulations.
