The list of symphonies in A-flat minor includes:
C major is a major scale based on C, consisting of the pitches C, D, E, F, G, A, and B. C major is one of the most common keys used in music. Its key signature has no flats or sharps. Its relative minor is A minor and its parallel minor is C minor.
E major is a major scale based on E, consisting of the pitches E, F♯, G♯, A, B, C♯, and D♯. Its key signature has four sharps. Its relative minor is C-sharp minor and its parallel minor is E minor. Its enharmonic equivalent, F-flat major, has six flats and the double-flat B, which makes it impractical to use.

Its relative major is F-flat major, which is usually replaced by E major. Its parallel major is D-flat major. Its direct enharmonic equivalent, C-sharp minor, is normally used.
Progressive tonality is the music compositional practice whereby a piece of music does not finish in the key in which it began, but instead 'progresses' to an ending in a different key or tonality. In this connection 'different key' means a different tonic, rather than merely a change to a different mode : Gustav Mahler's Second Symphony (1888–94), for example, which moves from a C minor start to an E-flat major conclusion, exhibits 'progressive tonality'—whereas Ludwig van Beethoven's Fifth Symphony (1804–08), which begins in C minor and ends in C major, does not. A work which ends in the key in which it began may be described as exhibiting 'concentric tonality'. The terms 'progressive' and 'concentric' were both introduced into musicology by Dika Newlin in her book Bruckner, Mahler, Schoenberg (1947).
