A major is a favored key in many musical genres for its inherently joyful and sonorous quality, making it ideal for conveying feelings of happiness and triumph. A major scale features three sharps in its key signature: F♯, C♯, and G♯.

From the A major scale, several triads (or chords) can be derived, each rooted on one of the scale’s seven notes, with the third and fifth notes above each root adding to form complete chords.
