The frequency of a pitch is derived by multiplying (ascending) or dividing (descending) the frequency of the previous pitch by the twelfth root of two (approximately 1.059463). [1] [2] For example, to get the frequency one semitone up from A 4 (A ♯4 ), multiply 440 Hz by the twelfth root of two.
May 6, 2014 · In theory it is easy, to get the frequency of the note other than A4=440Hz you just multiply/divide 440Hz by the proper number. For example, to get A2, you divide by 4 and get A2=110Hz.

For example, to get the frequency a semitone up from A4 (A♯4), multiply 440 by the twelfth root of two. To go from A4 to B4 (up a whole tone, or two semitones), multiply 440 twice by the twelfth root of two. For other tuning schemes refer to musical tuning. This list of frequencies is for a theoretically ideal piano.

The frequency needs to double every \displaystyle {12} 12 notes (because there are \displaystyle {7} 7 white notes and \displaystyle {5} 5 black notes in each octave.) Here is a graph of that relationship: frequency \displaystyle= {440}\times {2}^ { { {n}\text {/} {12}}} = 440× 2n/12. 10 20 -10 -20 500 1000 1500 2000 n freq.

This note frequency calculator is a convenient tool to determine the frequency of musical notes tuned in the twelve-tone equal temperament. In the text, you'll find the note frequency chart and a guide on how to use the note frequency converter.
And that's what makes each key sound unique! To be even more specific, each key on a piano is actually tuned to a specific frequency. That means that the string inside the piano is adjusted so that it vibrates at just the right speed to create the note you want to hear.
The Piano. The piano has 88 keys which span the frequency range 27.5 Hz (A0) to 4186 Hz (C8). The strings are sounded by hammer mechanisms which are activated by the keys. Held in a heavy cast iron frame, the strings pass over a bridge to a pin block by which the strings are tuned. The soundboard is a crucial element in the sound of the piano.
