a unit used in music to describe the ratio in frequency between notes. Equal to 1/12 octave, the half step measures the difference between adjacent notes in the standard 12-tone scale, as on a piano keyboard. Two notes differ in frequency by a half step if the higher one has frequency equal to 21/12 = 1.0595 times the frequency of the lower one.
(semitone) The interval between any two adjacent notes on a keyboard; the smallest interval in common use in Western music.
A pitch difference which is the equivalent of that produced by two adjacent keys on a piano.
the closest pitch above or below any given pitch
the musical interval between adjacent keys on a keyboard instrument
the distance on the piano between any two consecutive keys, i.e. B to C, C to C# to D, etc. In equal temperament the interval of the half step is constant; in just intonation and other temperaments half steps can vary widely.
Smallest interval used in the Western system, the octave divides into twelve such intervals; on the piano, the distance between any two adjacent keys, whether black or white. Also semitone.
A pitch difference of the amount that is present between adjacent keys on a piano.
Used to define the distance between a note that is one fret away from another note, ascending or descending i.e. equal in distance of B to C (ascending) or C to B (descending).
an incomplete step forward or backward
The distance from one key to the very closest key on the keyboard (Ex. C-C#, or E-F).
The smallest recognized interval in Western music. The distance represented by one fret on a guitar is a half step.
The distance between one key and the next adjacent key of the piano keyboard, including all black and white keys. It is also called an Interval of a Minor Second.
The smallest interval on the standard keyboard. The interval between two adjacent keys (incl. both black and white keys) is a half step.
