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 .
This note lies a chromatic semitone above A and a diatonic semitone below B, thus being enharmonic to B ♭ (French: si bémol). When calculated in equal temperament with a reference of A above middle C as 440 Hz, the frequency of the A ♯ above middle C is approximately 466.164Hz.

These 24 Preludes are based on a seven-note scale consisting of the six notes of the whole–tone scale with the addition of the perfect fourth [254] The sequence includes preludes in D#, G# and A#, which are normally considered theoretical keys as their key signatures include double sharps. Michelle Gorrell [255]

The intervals from the tonic (keynote) in an upward direction to the second, to the third, to the sixth, and to the seventh scale degrees of a major scale are called major. [1] A major scale is a diatonic scale. The sequence of intervals between the notes of a major scale is:

In music, letter notation is a system of representing a set of pitches, for example, the notes of a scale, by letters. For the complete Western diatonic scale , for example, these would be the letters A-G, possibly with a trailing symbol to indicate a half-step raise ( sharp , ♯ ) or a half-step lowering ( flat , ♭ ).
