Шаблон:Short description Шаблон:Infobox musical scale

A major (or the key of A) is a major scale based on A, with the pitches A, B, [[C♯ (musical note)|CШаблон:Music]], D, E, [[F♯ (musical note)|FШаблон:Music]], and [[G♯ (musical note)|GШаблон:Music]]. 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 Шаблон:Midsize (i.e. the flattened supertonic) requires both a flat and a natural accidental.

The A major scale is:

<score sound="1"> {

\omit Score.TimeSignature \relative c { 

 \key a \major \time 7/4 a4 b cis d e fis gis a gis fis e d cis b a2
 \clef F \key a \major

} } </score> In the treble, alto, and bass clefs, the GШаблон:Music in the key signature is placed higher than CШаблон:Music. However, in the tenor clef, it would require a ledger line and so GШаблон:Music is placed lower than CШаблон:Music.

History

Although not as rare in the symphonic literature as sharper keys (those containing more than three sharps), symphonies in A major are less common than in keys with fewer sharps such as 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, along with his 23rd Piano Concerto, and generally Mozart was more likely to use clarinets in A major than in any other key besides E-flat major.[1] Moreover, the climax part of Tchaikovsky's Violin Concerto is also in A major.

The key of A occurs frequently in chamber music and other music for strings, which favor sharp keys. Franz Schubert's Trout Quintet and Antonín Dvořák's Piano Quintet No. 2 are both in A major. Johannes Brahms, César Franck, and Gabriel Fauré wrote violin sonatas in A major. In connection to Beethoven's Kreutzer Sonata, Peter Cropper said that A major "is the fullest sounding key for the violin."[2]

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."[3]

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. Hector Berlioz complained about the custom of his day in which timpani tuned to A and E a fifth apart were notated C and G a fourth apart, a custom which survived as late as the music of Franz Berwald.[4]
