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 four flats.

The A major scale is:

\relative c'' { 
  \clef treble \key aes \major \time 7/4 \hide Staff.TimeSignature aes4 bes c des es f g aes g f es des c bes aes2

The relative minor is F minor. Its parallel minor, A minor, is usually replaced by G? minor, since A minor, which would contain seven flats, is not normally used. G major, its enharmonic, with eight sharps, including the Fdouble sharp, has a similar problem, and so A major is often used as the parallel major for G minor. (The same enharmonic situation occurs with the keys of D major and C minor.)

It was used quite often by Franz Schubert; twenty-four of Frédéric Chopin's piano pieces are in A major, more than any other key.

Compositions in A major

Beethoven chose A major as the key of the slow movement for most of his C minor works, a practice which Anton Bruckner imitated in his first two C minor symphonies and also Antonín Dvo?ák in his only C minor symphony.

Since A major was not often chosen as the main key for orchestral works of the 18th century, passages or movements in the key often retained the timpani settings of the preceding movement. For example, Beethoven's Symphony No. 5 in C minor has the timpani set to C and G for the first movement. With hand-tuned timpani, there is no time to re-tune the timpani to A and E for the slow second movement in A; accordingly, the timpani in this movement are reserved for the passages in C major. In Bruckner's Symphony No. 1 in C minor, however, the timpani are re-tuned between the first movement in C minor and the following in A major.

Charles-Marie Widor considered A major to be the second best key for flute music.[1]

A major was the flattest major key to be used as the home key for the keyboard and piano sonatas of Domenico Scarlatti, Joseph Haydn and Ludwig van Beethoven, with each of them using the key for two sonatas: Scarlatti's K. 127 and K. 130, Haydn's Hob XVI 43 and 46, and Beethoven's Op. 26 and Op. 110, while Franz Schubert used it for one piano sonata. It was also the flattest major key to be used for the preludes and fugues in Johann Sebastian Bach's Well-Tempered Klavier, as flatter major keys were notated as their enharmonic equivalents.

Felix Mendelssohn, Johann Nepomuk Hummel, John Field, and Friedrich Kalkbrenner each wrote one piano concerto in A (Mendelssohn's being for two pianos); they had the horns and trumpet tuned to E. Max Bruch's Concerto for Two Pianos in A minor has its last movement in A major, which is the parallel major; this concerto plays with the contrast between the two keys.

Other compositions in A major include:
