Once you’re familiar with the scale, you’ll do well to remember that the formula for a G# major chord (and any tonic major chord of any key) is 1-3-5 which gives the notes G#-B#-D# while the formula for an Ab major chord is 1-3-5 which gives the notes Ab-C-Eb.
while for Ab major, the Ab is a 1, the Bb is a 2 etc. Ab is more common than G#, so we’ll approach most of the chords below from the F# perspective.Įach of these notes (degrees of the scale) can be assigned a number as it ascends so you can use a helpful formula to work out chords from it. Hence why is you take a look at the scales above, each note is the enharmonic equivalent of each other, so if you played a G# major scale out of context, it would be completely impossible to determine whether it was G# or Ab.įor example, in a key with flattened notes, then you’ll (normally) be playing a Ab if you need to use that note, but in a key with sharps, then it’ll (normally) be a G#. Sort of… Technically a G# and an Ab are exactly the same, they just appear in different contexts. You may have noticed that we’re looking at two scales here. On a guitar, the 1/2 means the next fret is in the scale, and the 1 means there will be a fret in between the two notes. On a piano, the ‘1’ means that if you’re starting on the C, then there will be one note (Eb in this case) between your C and the next note of the scale (D), while the 1/2 means that the next note of the scale is directly next door (such as in the move from E-F in C major). 5 G Sharp / A Flat Minor 7 Guitar ChordĮvery major scale has the same theory behind it, building on a pattern of tones between the notes: 1-1-1/2-1-1-1-1/2.4 G Sharp / A Flat Major 7 Guitar Chord.
