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:
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.
By the end of the Baroque era, however, conventional academic views of B minor had shifted: Composer-theorist Francesco Galeazzi (1758–1819) [2] opined that B minor was not suitable for music in good taste. Beethoven labelled a B-minor melodic idea in one of his sketchbooks as a "black key". [3]
Beethoven's Piano Sonata in E Minor, Op. 90, contains a passage where a B ♭ becomes an A ♯, altering its musical function. The first two bars of the following passage unfold a descending B ♭ major scale. Immediately following this, the B ♭ s become A ♯ s, the leading tone of B minor: Beethoven Sonata in E Minor Op. 90, first movement ...
The augmented scale, also known in jazz theory as the symmetrical augmented scale, [3] is so called because it can be thought of as an interlocking combination of two augmented triads an augmented second or minor third apart: C E G ♯ and E ♭ G B. It may also be called the "minor-third half-step scale", owing to the series of intervals ...
The A harmonic minor scale can be used on the chords of a piece in A minor, especially on the minor ii–V–i chord progression. One of the most common uses of the harmonic minor scale is its fifth mode (phrygian dominant scale), which is a frequently used over dominant chords.
Ascending intervals are indicated by a positive value, and descending intervals by a negative one. [3] One can also measure the distance between two pitches without taking into account direction with the unordered pitch interval, similar to the interval of tonal theory. This may be defined as:
