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 (see below: Scales and keys).

Its relative minor is F-sharp minor and its parallel minor is A minor. The key of A-major is the only key where a Neapolitan sixth chord on requires both a flat and a natural accidental.

Although not as rare in the symphonic literature as sharper keys, examples of symphonies in A major are not as numerous as for D major or G major. Beethoven's Symphony No. 7, Bruckner's Symphony No. 6 and Mendelssohn's Symphony No. 4 comprise a nearly complete list of symphonies in this key in the Romantic era. Mozart's Clarinet Concerto and Clarinet Quintet are both in A major.

In chamber music, A major occurs more often. Both Brahms and Franck wrote violin sonatas in A major.

According to Christian Friedrich Daniel Schubart, A major is a key suitable for "declarations of innocent love, ... hope of seeing one's beloved again when parting; youthful cheerfulness and trust in God."

For orchestral works in A major, the timpani are typically set to A and E a fifth apart, rather than a fourth apart as for most other keys.
