What is a G#maj7 chord?
A major 7th chord stacks the root, major 3rd, perfect 5th and major 7th — root plus all the bright intervals. The interval between the 7th and the root (a half step) creates a dreamy, unresolved color that's softer than the bluesy tension of a dominant 7th. Major 7ths are the signature sound of bossa nova, jazz ballads and dreamy pop verses.
Notes in the chord: G# – C – D# – G
Intervals: Root, 3, 5, 7 (measured from the root)

When to use a major 7th chord
In the key of G# major, G#maj7 is the tonic (I) — the chord progressions here resolve home to. Use major 7ths as the I chord (Imaj7) for a Steely Dan / Ben Folds / bossa-nova feel, or as the IV chord (IVmaj7) for a softer cadence. They appear constantly in jazz standards (e.g. 'Misty', 'Girl from Ipanema') and any pop song reaching for sophistication. Substitute a plain major chord with maj7 to add color without changing the chord's function.
