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.

Based on their interval patterns, scales are put into categories including pentatonic, diatonic, chromatic, major, minor, and others. A specific scale is defined by its characteristic interval pattern and by a special note, known as its first degree (or tonic). The tonic of a scale is the note selected as the beginning of the octave, and ...
This is seen, for example, in melodic minor scale harmony, which is based on the seven rotations of the ascending melodic minor scale, yielding some interesting scales as shown below. The "chord" row lists tetrads that can be built from the pitches in the given mode [ 80 ] (in jazz notation , the symbol Δ is for a major seventh ).
The intervals between the notes of a harmonic minor scale follow the sequence below: whole, half, whole, whole, half, augmented second, half. While it evolved primarily as a basis for chords, [5] the harmonic minor with its augmented second is sometimes used melodically.
For example, the interval between C and E (four half steps) is a major third, which can imply a C major chord, made up of the notes C, E and G. [3] In a triadic context chords with omitted thirds may be considered "indeterminate" triads. [4] Play ⓘ Melodic and harmonic intervals, respectively above and below. Play ⓘ
