A-flat major is a weighty, ponderous key with a particular gravity to it, a
shadowy, melancholic character. Unlike E-flat Major, A-flat Major is ill-suited
for grand narratives. It is not a very energetic key, but more suitable for contemplation. It is
especially fitting for bass tones because of its richness. Its color is a deep shade of bronze.
A-flat major is a key with A-flat as root and consists of the pitches A♭, B♭, C, D♭, E♭, F, and G. Its
key signature has four flats. Its relative minor is F minor. Its
parallel minor, A-flat minor, is
usually written instead as the enharmonic key of G-sharp minor, since
A-flat minor contains seven flats and G-sharp minor only contains five
sharps.
A-flat 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 Clavier, as flatter major keys were notated as their enharmonic equivalents.
Beethoven chose A-flat 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 Dvořák in his only C minor
symphony. The second movement of Haydn's 43rd symphony in E-flat major
is in A-flat major. A-flat Major was Chopin’s favorite key,
probably because of the contemplative and lyrical qualities. He used
this key in many of his works, particularly in his waltzes.
Felix Mendelssohn, Johann Nepomuk Hummel, John Field, and Friedrich Kalkbrenner each wrote one piano concerto in A-flat (Mendelssohn's is for two pianos); they had the horns and trumpet tuned to E-flat. Max Bruch's Concerto for Two Pianos in A-flat minor has its last movement in A-flat major, which is the parallel major; this concerto plays with the contrast between the two keys. (Unfortunately, none of these piano concertos is available in a suitable version on YouTube).
Characteristic compositions in A-flat major:
Johann Sebastian Bach, Prelude and Fugue Nr 17 BWV 862 in A-flat Major (Das Wohltemperierte Klavier, Book I)

Joseph Haydn, Piano Sonata No 31 in A flat major, Hob XVI:46
The extended second movement is stoically expressive even with its extensive ornamentation. With the extreme tonality goes a peculiar intimacy of expression: from the delicate contrapuntal opening, with the bass descending passacaglia-style, making this one of the most subtle and poetic of all Haydn’s slow movements
With its catchy, quicksilver main theme, the compact sonata-form finale the hell-bent-for-speed last movement provides a glorious physical release.

Ludwig van Beethoven, Piano Sonata No. 31 op. 110 in A-flat major
The first movement is in sonata form, opening with a deceptively simple idea (marked - unusually for Beethoven, at this stage of his life - con amabilità), a theme that forms the basis for much of the motivic working of the whole Sonata. The second subject group is an amalgam of short ideas in E flat, one in the extreme high register of the instrument, another a brief alternation of rising scales and falling fifths, and the last a more gentle codetta idea that leads into a reprise of the first subject - which is in effect the brief, 16-bar development. The scherzo turns to F major, and is again remarkably simple in its outline and almost joky ideas. Its trio is in D flat major.
The real heart of this Sonata is its finale. It opens with a recitative, full of changes of tempo and figuration, before the Adagio proper gets under way - a tearful song over incessant semiquaver chords. This leads straight into a three-voice Allegro fugue, and the genius of Beethoven's scheme becomes clear when the fugue subject recalls the outline of the opening melody of the first movement - a subtle association by suggestion rather than outright imitation. The fugue dissolves into the Arioso and returns with the fugue subject turned upside down, leading into a triumphant coda.

Frédéric Chopin, Ballade No. 3 in A-flat Major, Op. 47
Like many of Chopin's works set in A-flat major, Op. 47 is probably the richest among the ballads. In 6/8 Allegretto throughout, it includes three themes with several variations. From the single E-flat of the dominant, the 1st measure already strikes a wide arc. The relaxed mood loses itself in opposing dissonances and sforzatos. Mezza voce appears the again tranquil second theme in F major. It is varied twice in C major and once in A flat major. A wide arpeggio begins the furious F minor section, which returns in A flat major. It is followed by a quiet C-sharp minor idea, restless on the left, which turns to a luminous C-sharp major. It is varied in a grandiose modulation with arpeggiated octave chords on the right and wide octave leaps on the left. Varying once again in grumbling dissonances, it finds its way - for the first time since the beginning - to the A-flat major theme, this time in magnificent octave chords.

Frédéric Chopin Waltz op. 69 No. 1 “L’Adieu”
The waltz is played Lento and is in Rondo form. The theme is a melody in a chromatic descending progression, which begins in F minor and changes to A-flat major in the 8th bar. There are some mazurka-like rhythms and three-degree chords in the middle of the melody, and some dance-like fragments.

Franz Liszt, Liebestraum No 3 in A-flat major
Liebestraum No. 3 in A-flat major is the last of the three and the most popular. It can be considered as split into three sections, each divided by a fast cadenza requiring dexterous finger work and a very high degree of technical ability. The same melody is used throughout the piece, each time varied, especially near the middle of the work, where the climax is reached.
Antonín Dvořák, String Quartet No. 14 in A-Major Op. 105
In the last nine years of his life, Dvořák would write no more chamber music, only symphonic poems and operas. In terms of mood, opus 105 is the milder, more relaxed counterpart to opus 106. It is less densely constructed; at the same time, the Slavonic influence is more pronounced.
Adagio ma non troppo - Allegro appassionato
The only quartet - besides No. 2 - that begins with a slow introduction.
Molto vivace
Scherzo with furiant-like rhythm and a lilting trio in D-flat major.
Lento e molto cantabile
Simple effortless song with a more chromatic middle section.
Allegro non tanto
In terms of rhythm, this recalls the Polka. It is cheerful, freer and looser than the 13th string quartet' .
The Fourteenth String Quartet is a worthy conclusion to Dvořák's chamber music oeuvre.
Shanghai String Quartet
Edward Elgar, Symphony No. 1 in A-flat Major
The symphony consists of four movements.
Andante nobilmente e semplice - Allegro
The slow introduction to the extended opening movement introduces a theme of solemn, hymnal character that serves as a motto for the entire work and recurs throughout the rest. The Allegro section is in D minor, a key that is extremely distant in kinship from the initial A-flat major because of the tritone spacing of the root notes.
Allegro molto
The scherzo oscillates between sections that are sometimes hectic, sometimes rhythmically aggressive, and more supple (trio-like) passages.
Adagio
After a period of calming, the songful Adagio follows attacca, its theme copying note-for-note the theme of the Scherzo (in slower motion).
Lento - allegro
The expansive and characterful complex final movement ends with a triumphant apotheosis of the motto theme in an effective final sonic fireworks display.

Dmitri Shostakovich, String Quartet No. 10 in A-flat major Op. 118
The work has four movements:
I. Andante
The first movement is in sonata rondo form and makes use of soft dynamics. Opening with a four-note motif on the solo violin, the movement is largely written in E minor, a minor sixth away from the main key of A-flat major. This E minor/A-flat major dialogue recurs throughout the quartet. The movement ends morendo, denoting gradually dying away in volume.
II. Allegretto furioso
The second movement is in E minor. The emotional indicator 'furioso' is unique in Shostakovich's string quartets. Its beginning, four whole tone steps, references a subject used by Shostakovich in his Fifth Symphony and Eighth String Quartet.
III. Adagio (attacca)
The third movement is written in A minor, a semitone away from the tonic A-flat major, although it also employs the A-flat major and E minor tonalities which recur throughout the work. It is written in the passacaglia form, frequently used in Shostakovich's music. The passacaglia theme is developed, played with and without ground bass, and with added bars and beats throughout the movement.
IV. Allegretto – Andante
The fourth movement is played continuous from the third. It is written in A-flat major, the tonic key of the work. It also employs D minor, creating dissonance a tritone away from the tonic. It is written in sonata rondo form and makes extensive use of drones and folk song rhythms. In this movement, the themes of each of the preceding three movements are heard again, against the new rondo theme, including the passacaglia heme of the third movement, which is played fortississimo, creating a contrast against the movement's largely muted texture. The movement ends, marked morendo as with the first movement, creating an uncertain finish.
