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.
the ascending melodic minor scale or jazz minor scale (also known as the Ionian ♭ 3 or Dorian ♯ 7): this form of the scale is also the 5th mode of the acoustic scale. the descending melodic minor scale: this form is identical to the natural minor scale . The ascending and descending forms of the A melodic minor scale are shown below:
Melodic minor scale (ascending) on A Play ⓘ In traditional classical theory, the melodic minor scale has two forms, as noted above, an ascending form and a descending form. Although each of these forms of itself comprises seven pitches, together they comprise nine, which might seem to call into question the scale's status as a heptatonic scale.
In classical music from Western culture, a diminished third (Play ⓘ) is the musical interval produced by narrowing a minor third by a chromatic semitone. [ 1 ] [ 4 ] For instance, the interval from A to C is a minor third, three semitones wide, and both the intervals from A ♯ to C, and from A to C ♭ are diminished thirds, two semitones wide.
A semitone, also called a minor second, half step, or a half tone, [3] is the smallest musical interval commonly used in Western tonal music, [4] and it is considered the most dissonant [5] when sounded harmonically.
The chromatic circle is useful because it represents melodic distance, which is often correlated with physical distance on musical instruments. For instance, assuming 12-tone equal temperament, to move from any C on a keyboard to the nearest E, one must move up four semitones, corresponding to four clockwise steps on the chromatic circle.
Meantone refers to meantone temperament, where the whole tone is the mean of the major third. In general, a meantone is constructed in the same way as Pythagorean tuning, as a stack of fifths: the tone is reached after two fifths, the major third after four, so that as all fifths are the same, the tone is the mean of the third.
