About

The F♯ major 7th (F♯–A♯–C♯–E♯) adds a major seventh to the major triad. Unlike the dominant 7 there is no tritone — the E♯ sits a half step below the root, creating a gentle, unresolved shimmer rather than a strong directional pull. This makes maj7 a tonic or subdominant color, used to add sophistication without urgency. The major 7th interval itself is the defining tone; the fifth can be omitted. On guitar, shell voicings (1–3–7) are efficient and common in jazz. The half step between E♯ and the root is part of the appeal — a tension that does not demand resolution. Compared to F♯7, maj7 is relaxed and expansive; compared to F♯, more harmonically lit-from-within.
