Piano Pitch

Pitches Associated with Piano

Based upon the piano being tuned to A440

A440 is considered the international concert pitch for the A above middle C on a piano keyboard.  There are however variations on this depending upon the orchestra. Some orchestras prefer A442, claiming the strings sound better tuned slightly higher than “concert pitch”.

Theoretical fundamental piches of all eighty-eight notes. The box includes the twelve pitches of the temperament octave (in red) .This table was computed with a calculator by multiplying each successive half step by 1.0594631 (the twelfth root of two). Although the above pitches are rounded off to three places, computations were carried out to six places (five places, from C6 up).

For those that are curious, the lowest note on the piano is A sounding at 27.500 hz and the highest is the top C sounding at 4186.009 hz (cycles per second).
A440 concert pitch refers to tuning the A above middle C to 440.000 hz, shown in
blue above.
(Based on the standard 88 note keyboard)
