Interval (music) In music theory, an interval is a difference in pitch between two sounds. [ 1] An interval may be described as horizontal, linear, or melodic if it refers to successively sounding tones, such as two adjacent pitches in a melody, and vertical or harmonic if it pertains to simultaneously sounding tones, such as in a chord. [ 2 ...
In music, an interval ratio is a ratio of the frequencies of the pitches in a musical interval. For example, a just perfect fifth (for example C to G) is 3:2 ( Play ⓘ ), 1.5, and may be approximated by an equal tempered perfect fifth ( Play ⓘ) which is 2 7/12 (about 1.498). If the A above middle C is 440 Hz, the perfect fifth above it would ...
Majorand minormay also refer to scales and chords that contain a major thirdor a minor third, respectively. A major scaleis a scale in which the third scale degree(the mediant) is a major third above the tonicnote. In a minor scale, the third degree is a minor third above the tonic. Similarly, in a major triador major seventh chord, the third ...

In music theory, a perfect fifth is the musical interval corresponding to a pair of pitches with a frequency ratio of 3:2, or very nearly so. In classical music from Western culture, a fifth is the interval from the first to the last of the first five consecutive notes in a diatonic scale. [ 1] The perfect fifth (often abbreviated P5) spans ...
Tuning is the process of adjusting the pitch of one or many tones from musical instruments to establish typical intervals between these tones. Tuning is usually based on a fixed reference, such as A = 440 Hz. The term " out of tune " refers to a pitch/tone that is either too high ( sharp) or too low ( flat) in relation to a given reference pitch.
Definition. the ratio of the area under sole cropping to the area under intercropping needed to give equal amounts of yield at the same management level. It is the sum of the fractions of the intercropped yields divided by the sole-crop yields. For a scenario where a total of crops are intercropped, the land equivalent ratio LER can be ...
