Introduction

An interval is the distance in pitch in between two notes. The smallest interval is a semitone. This is the distance between, for example, C and also C#.

You are watching: The distance in pitch between any two tones is called

An term is the relationship in between two different musical pitches. Because that example, in the melody “Twinkle Twinkle tiny Star,” the first two notes (the first “twinkle”) and also the second two note (the 2nd “twinkle”) room at the interval of one fifth. What this way is the if the first two notes were the pitch C, the second two notes would certainly be the pitch “G”—four scale notes, or seven chromatic note (a perfect fifth), over it.

Compound Intervals

In the music scale, there room twelve pitches; the surname A, B, C, D, E, F, and also G. As soon as the intervals surpass the perfect Octave (12 semitones), this intervals are dubbed compound intervals, i m sorry include particularly the 9th, 11th, and 13th intervals—widely used in jazz and blues music.

Compound intervals room formed and also named together follows:

2nd + Octave = 9th3rd + octave = 10th4th + Octave = 11th5th + octave = 12th6th + Octave = 13th7th + octave = 14th

Consonant and also Dissonant Intervals

Consonance in music, is once a mix of note sounds pleasant. Instances of consonant intervals is music played in unison, major and young thirds, perfect fourths and also fifths, major and young sixths, and also octaves.

Dissonance is a combination of notes the sound unpleasant or harsh. Dissonant interval instances are major and boy seconds, tritone, and major and boy sevenths.

The consonant intervals are considered the perfect unison, octave, fifth, 4th and major and minor third and sixth, and their link forms. An interval is referred to as “perfect” once the harmonic relationship is found in the natural overtone collection (namely, the unison 1:1, octave 2:1, 5th 3:2, and also fourth 4:3). The other basic intervals (second, third, sixth, and also seventh) are dubbed “imperfect” because the harmonic relationships are not discovered mathematically exact in the overtone series. In classical music the perfect fourth over the bass may be taken into consideration dissonant as soon as its duty is contrapuntal.

Other intervals, the second and the saturday (and your compound forms) are thought about dissonant and require resolution (of the produced tension) and also usually ready (depending on the music style used). It should be listed that the effect of dissonance is perceived fairly within musical context: because that example, a major seventh expression alone (i.e. C up to B) might be viewed as dissonant, yet the exact same interval as component of a significant seventh chord might sound reasonably consonant. A tritone (the expression of the fourth step to the seventh step of the major scale, i.e. F to B) sounds very dissonant alone, but less so within the paper definition of a leading seventh chord (G7 or D♭7 in that example).
