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]
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 .

The diatonic scale (seven notes)—this includes the major scale and the natural minor; The melodic and harmonic minor scales (seven notes) These scales are used in all of their transpositions. The music of this period introduces modulation, which involves systematic changes from one scale to another. Modulation occurs in relatively ...
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 , ♭ ).
Fixed do uses the syllables re–mi–fa–sol–la–ti specifically for the C major scale, while movable do labels notes of any major scale with that same order of syllables. Alternatively, particularly in English- and some Dutch-speaking regions, pitch classes are typically represented by the first seven letters of the Latin alphabet (A, B ...
