piano chord
G♯
G♯1B♯3D♯5
A major third and a perfect fifth over the root.
Written the other way round it is A♭ — the same twelve keys on a piano, a different piece of notation.
What is true of it
G♯ is G♯, B♯ and D♯ — 1, 3 and 5 counted from G♯.
On an instrument that cannot reach all 3, the 5 goes first, in that order.
