Music notation systems − Music frequencies of equal temperament tuning Naming of musical notes and piano keys.Piano (typically containing 88 keys) in twelve-tone equal temperament, with the 49th key, the fifth A (called A4), tuned to 440 Hz (referred to as A440). To better understand why today’s pianos are 88 keys, it’s important to understand exactly how the instrument came to be. 88 keys have been the standard since Steinway built theirs in the 1880s. Adding more piano keys removed the limits on what kind of music could be performed on the instrument. Pianos have 88 keys because composers wanted to expand the range of their music. Thus, the A0 key also produces a tone at 55.0 Hz, which is one octave higher than the fundamental The second overtone is at 82.5 Hz. A piano key has harmonic overtones at integer multiples of its fundamental frequency. What are the frequencies of notes on a piano?įrequency of 27.5 Hz. “A-440” can be described as that of the musicians. From a tuning point of view the frequency A over middle C should be 440 Hz according to today’s contemporary standards. The range of frequencies are between 5 MHz and 47 MHz.
Piano notes range in frequency from 27 to 31 during pitch ranges.
