A related interval is the octave, which include the same notes as the unison but of different pitches. The octave interval is the one produced when the length of the string is divided in half keeping it at the same tension, thus the frequency is multiplied by two, 440 x 2 = 880 Hz. How many Hz is an octave?Īn octave (in English, octave) is a frequency band that is located between a first frequency and another that is twice this frequency, such as from 1000 to 2000 Hz, or from 707 to 1414 Hz (which corresponds to the band of octave centered at 1000 Hz 1). When two notes are played together and are an octave apart, they sound harmonious and consonant. Musicians use octaves to create harmonies and melodies. From 100 Hz to 200 Hz there is an octave, as is the interval from 2000 Hz to 4000 Hz. The octave is the simplest interval in music, and it is the foundation of all other intervals. What is the ratio of the eighth musical note?įor example, an octave is a musical interval defined by the ratio of 2:1, regardless of the starting frequency. For instance: C 220 is a note whose frequency is 220Hz, so we can define one octave including many sounds, all these sounds have a frequency higher than 220Hz and lower than 440Hz. If a sound has a fundamental frequency of 2640 Hz, it will be one octave higher than one whose frequency is 1320 Hz. In music, an octave is a sound interval, grouping all notes whose frequencies are between a frequency reference f and the double 2xf. It can be the interval that exists between a pair of sounds that have frequencies that maintain a 2-1 link. Mathematically speaking, two notes (two sounds with a defined frequency) form an octave when the frequency of one of the two notes is twice that of the other note that forms that octave. This results in a space that is known as an octave being created between the two pitches. This means that the octave represents a twofold increase in the rate of vibration. Octave is the musical interval that runs through eight degrees of a musical scale. To provide a more in-depth explanation, an octave is the interval that is created between two pitches when the frequency of one pitch is doubles that of the other pitch.
