About this chord
Its formula is 1 3 ♯5: the major third (M3) and augmented fifth (A5) above the root, B♭.
Counted in semitones from B♭, its notes are 0, 4, 8.
An augmented chord stacks two major thirds. Its raised fifth sounds unresolved and often moves up by a semitone into the next chord.
On the piano it uses the same keys as A♯aug (A♯ C𝄪 E𝄪). This page spells it B♭aug, which reads more simply.
In harmonic minor it is III+ in G minor.
In root position, play it with fingers 1-3-5 in the right hand, or 5-3-1 in the left hand (1 is the thumb, 5 the little finger).
Find the root first, place the other fingers over the coloured keys, then press them all together so every note sounds at the same time.
