![]() ![]() It replaced the earlier method of using simple frequency ratios to divide up the octave, which had great limitations when trying to transpose music from one key to another (more on what this means later). Since then, the music of the western world has been based on the notes of the Chromatic scale.Įqual temperament tuning was a major breakthrough in the development of music. The chromatic Scale consists of 12 notes each note is separated from the next by the interval of a semitone (or half step). This method of dividing the octave using the twelfth root of two is known as equal temperament tuning, pioneered several centuries ago in the time of JS Bach. Colors, in fact, are also made up from different frequencies, those of light waves.īecause notes repeat in each octave, the term 'chromatic scale' is often used for just the twelve notes of an octave. ![]() In this sense, chromatic scale means 'notes of all colors'. The set of all musical notes is called the Chromatic Scale, a name which comes from the Greek word chrôma, meaning color. We can do this in both directions (multiplying upwards and dividing downwards) to calculate the frequency of every musical note. The difference in pitch between adjacent notes is called a semitone.Īfter doing this for twelve notes, you end up with twice the frequency, which is the note one octave up from the starting note. The frequency of a note, when multiplied by the twelfth root of two, gives the frequency of the next note up. The range of frequencies in between is divided up into the twelve steps that give us all of our notes. Remember that with notes one octave apart, the higher note has double the frequency of the lower note. Such a sequence of pitches is produced, for example, by playing all the black and white keys of a piano in order. The chromatic scale is a musical scale with twelve pitches, each a semitone, also known as a half-step, above or below its adjacent pitches. This is the number that, when multiplied by itself twelve times, gives a result of two. Chromatic scale on C: full octave ascending and descending A chromatic scale consists of an ascending or descending sequence of pitches, always proceeding by semitones. There is a magic number in western music, known as the twelfth root of two, and it has a value of approximately 1.0595. The chromatic scale is all-embracing, and the only scale that contains all the twelve notes (aka pitches.) Consequently, theres just one chromatic scale on.
