What is retrograde inversion in music?
Retrograde inversion is a musical term that literally means “backwards and upside down”: “The inverse of the series is sounded in reverse order.” Retrograde reverses the order of the motif’s pitches: what was the first pitch becomes the last, and vice versa.
What is the difference between retrograde and inversion in music?
The retrograde is the prime form backward. The inversion is the original row with all intervals in the row inverted (going in the opposite direction of the original).
How do you do retrograde inversions?
So, to invert the prime form, subtract each number (except zero) from 12. To get the retrograde, list the prime form backwards, starting with the last pitch class and reading right to left. To get the retrograde inversion, list the inversion form backwards, reading the notes from right to left.
What is retrograde melody?
A melodic line that is the reverse of a previously or simultaneously stated line is said to be its retrograde or cancrizans (“walking backward”, medieval Latin, from cancer, crab). An exact retrograde includes both the pitches and rhythms in reverse.
What is retrograde form?
A retrograde form of the row takes a prime form and exactly reverses the pitch classes. Its interval content, then, are the reverse of the prime forms. Retrograde forms are labeled R followed by a subscript denoting the last pitch class in the row.
What are inversions chords?
A chord inversion occurs when any note other than the root of a basic chord is played down at the bass. For example, a basic C major chord includes the notes C, E and G. C, the chord note name and root, is placed at the bottom of the chord.
What is inversions in music?
inversion, in music, rearrangement of the top-to-bottom elements in an interval, a chord, a melody, or a group of contrapuntal lines of music. The inversion of chords and intervals is utilized for various purposes, e.g., to create a melodic bass line or (with certain chords) to modulate to a new key.

Retrograde inversion. Retrograde inversion is a musical term that literally means “backwards and upside down”: “The inverse of the series is sounded in reverse order.”. Retrograde reverses the order of the motive’s pitches: what was the first pitch becomes the last, and vice versa. This is a technique used in music,…
Which is the transposition of RI in retrograde inversion?
Note that IR is a transposition of RI, the pitch class between the last pitches of P and I above RI. Other compositions that include retrograde inversions in its rows include works by Tadeusz Baird and Karel Goeyvaerts.
What kind of inversion does Igor Stravinsky use?
In his late twelve-tone works, however, Igor Stravinsky preferred the opposite order, so that his row charts use inverse retrograde (IR) forms for his source sets, instead of retrograde inversions (RI), although he sometimes labeled them RI in his sketches. For example, the forms of the row from Requiem Canticles are as follows:
