An interval is inverted by raising or lowering either of the notes by one or more octaves so that the higher note becomes the lower note and vice versa. For example, the inversion of an interval consisting of a C with an E above it (the third measure below) is an E with a C above it – to work this out, the C may be moved up, the E may be lowered, or both may be moved.
In music, a sequence is the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice. [1] It is one of the most common and simple methods of elaborating a melody in eighteenth and nineteenth century classical music [1] (Classical period and Romantic music). Characteristics of sequences: [1]
Inversional combinatoriality is a relationship between two rows, a principal row and its inversion. The principal row's first half, or six notes, are the inversion's last six notes, though not necessarily in the same order. Thus, the first half of each row is the other's complement. The same conclusion applies to each row's second half as well.
The interval number and the number of its inversion always add up to nine (4 + 5 = 9, in the example just given). The inversion of a major interval is a minor interval, and vice versa; the inversion of a perfect interval is also perfect; the inversion of an augmented interval is a diminished interval, and vice versa; the inversion of a doubly ...
In music theory, retrograde inversion is a musical term that literally means "backwards and upside down": "The inverse of the series is sounded in reverse order." [ 1 ] Retrograde reverses the order of the motif 's pitches : what was the first pitch becomes the last, and vice versa. [ 2 ]
In traditional theory concepts like voicing and form include ordering; for example, many musical forms, such as rondo, are defined by the order of their sections. The permutations resulting from applying the inversion or retrograde operations are categorized as the prime form's inversions and retrogrades , respectively.
However, the defense has been made that theory was not created to fill a vacuum in which existing theories inadequately explained tonal music. Rather, Forte's theory is used to explain atonal music, where the composer has invented a system where the distinction between {0, 4, 7} (called 'major' in tonal theory) and its inversion {0, 3, 7 ...
2 or V 2 its third inversion (F–G–B–D). [11]: 79–80 In the United Kingdom, there exists another system where the Roman numerals are paired with Latin letters to denote inversion. [14] In this system, an “a” suffix is used to represent root position, “b” for first inversion, and “c” for second inversion.
