| | A-flat major - Wikipedia, the free encyclopedia |
 | | A-flat major is the flattest major key Domenico Scarlatti used in his keyboard sonatas, though he used it only twice, in K. 127 and K. Felix Mendelssohn and John Field each wrote one piano concerto in A-flat (Mendelssohn's being for two pianos); they had the horns and trumpet tuned to E-flat. |
 | | Since A-flat 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. |
 | | A-flat major is a major scale based on A-flat, consisting of the pitches A-flat, B-flat, C, D-flat, E-flat, F, G, and A-flat. |
