A major
Major key and scale based on the note A / From Wikipedia, the free encyclopedia
A major (or the key of A) is a major scale based on A, with the pitches A, B, C♯, D, E, F♯, and G♯. Its key signature has three sharps. Its relative minor is F-sharp minor and its parallel minor is A minor. The key of A major is the only key where the Neapolitan sixth chord on (i.e. the flattened supertonic) requires both a flat and a natural accidental.
