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.
There is a long tradition in classical music of writing music in sets of pieces that cover all the major and minor keys of the chromatic scale. These sets typically consist of 24 pieces, one for each of the major and minor keys (sets that comprise all the enharmonic variants include 30 pieces). Examples include Johann Sebastian Bach 's The Well ...
The color schemes above divide the 12 basic notes of the chromatic scale into groups in different ways: Piano (7–5): two asymmetrical groups of 7 (white keys) and 5 (black keys) Whole Tone Scale (6–6): two symmetrical groups of notes a major second apart (6 notes per group)
This scale is known as the Pythagorean diatonic and is the scale that Plato adopted in the construction of the world soul in the Timaeus (36a-b). [12] The next notable Pythagorean theorist known today is Archytas, contemporary and friend of Plato, who explained the use of arithmetic, geometric and harmonic means in tuning musical instruments.
Chromatic scale drawn as a circle The diatonic scale notes (above) and the non-scale chromatic notes (below) [2] The twelve notes of the octave—all the black and white keys in one octave on the piano—form the chromatic scale. The tones of the chromatic scale (unlike those of the major or minor scale) are all the same distance apart, one ...

Scale (music) The C major scale, ascending and descending. In music theory, a scale is "any consecutive series of notes that form a progression between one note and its octave ", typically by order of pitch or fundamental frequency. [1][2] The word "scale" originates from the Latin scala, which literally means "ladder".
