Theory behind the chord
Major chords sound bright and settled. They are built from a root, a major third and a perfect fifth, and they carry most of the resolution points in pop, rock and folk. On G# this structure sits on the root G#, so the degrees 1 – 3 – 5 map onto G#, C and D#. G# is the I chord in the key of G# major, the V chord in D# major and the IV chord in C# major. Its relative minor is Fm, which shares the same set of notes. The most common progression it appears in is G# – Fm – C# – D#.
