The G# major scale is a seven-note scale that follows a specific pattern of whole steps and half steps. Key signature: 6 sharps (A#, B#, C#, D#, E#, F##) The G# major scale has some tricky notes like B# and E#, which are enharmonic to C and F, respectively. You might encounter these odd sharps in notation and music theory, but they’re used to preserve the structure of the scale according to the rules of major scale construction.
