A is a musical note equivalent to 440 Hz in typical A440 tuning. It is the sixth note of La and the tenth semitone of the fixed-do solfège . Its enharmonic equivalents are B ♭ ♭ (B double flat) which is a diatonic semitone above A ♭ and G (G double sharp) which is a diatonic semitone below A ♯ .

This list of frequencies is for a theoretically ideal piano. On an actual piano, the ratio between semitones is slightly larger, especially at the high and low ends, where string stiffness causes inharmonicity, i.e., the tendency for the harmonic makeup of each note to run sharp.

Cubase, Akai, and ProTools are starting differently at octave −2, or octave 1. That's not the standard. The first tone is the note A0 and that is 27.5 Hz. The classical music world is counting this way. The tuning pitch for the Western music (concert pitch), is 440 Hz. It is named A4 or a’.

Note Frequency Calculator and Player. Here is a utility courtesy of Colin Crawley which will calculate the frequencies of notes and can handle tunings other than A = 440Hz. It can also play the notes, so is useful as a tuning note reference. It works on Windows and Linux.

The twelfth key to the right of A0 is A1, counting both the black and white keys. The A1 note has a fundamental frequency of 55.0 Hz. The A1 note is thus one octave higher than the A0 note, in terms of their respective fundamental frequencies.
