Piano key frequencies. This is a list of the fundamental frequencies in hertz (cycles per second) of the keys of a modern 88-key standard or 108-key extended piano in twelve-tone equal temperament, with the 49th key, the fifth A (called A 4), tuned to 440 Hz (referred to as A440). [ 1 ][ 2 ] Every octave is made of twelve steps called semitones.
An 88-key piano keyboard, with the octaves numbered and middle C (cyan) and A440 (yellow) highlighted. The table below gives notation for pitches based on standard piano key frequencies: standard concert pitch and twelve-tone equal temperament.
Piano tuning is the process of adjusting the tension of the strings of an acoustic piano so that the musical intervals between strings are in tune. The meaning of the term 'in tune', in the context of piano tuning, is not simply a particular fixed set of pitches. Fine piano tuning requires an assessment of the vibration interaction among notes ...
A440 (pitch standard) A440, piano and violin. A440 (also known as Stuttgart pitch[1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
The Railsback curve contrasts a theoretically correct equal-tempered piano tuning against one that compensates for a piano's inharmonicity. The Railsback curve, first measured by O.L. Railsback, expresses the difference between inharmonicity-aware stretched piano tuning, and theoretically correct equal-tempered tuning in which the frequencies of successive notes are related by a constant ratio ...
This is the most common tuning system used in Western music, and is the standard system used as a basis for tuning a piano. Since this scale divides an octave into twelve equal-ratio steps and an octave has a frequency ratio of two, the frequency ratio between adjacent notes is then the twelfth root of two, 2 1/12 ≋ 1.05946309... .
The piano is a keyboard instrument that produces sound when its keys are depressed, through engagement of an action whose hammers strike strings. Modern pianos have a row of 88 black and white keys, tuned to a chromatic scale in equal temperament. A musician who specializes in piano is called a pianist.
C (musical note) C or Do is the first note of the C major scale, the third note of the A minor scale (the relative minor of C major), and the fourth note (G, A, B, C) of the Guidonian hand, commonly pitched around 261.63 Hz. The actual frequency has depended on historical pitch standards, and for transposing instruments a distinction is made ...
