A melodic line that is the opposite of one that was said before or at the same time is referred to as its retrograde or cancrizans (“walking backward”, medieval Latin, from cancer, crab). Pitch and rhythm are both reversed in an exact retrograde. Even more precisely, a retrograde can reverse the shape of the notes themselves, but this is only conceivable in electronic music. Some composers opt to retrograde either the rhythms or only the pitches of a musical line. Reversal of the pitch classes alone, regardless of the melodic contour produced by their registral placement, is viewed as a retrograde in twelve-tone music.

What does the musical term retrograde mean?
The phrase “the inverse of the series is sounded in reverse order” is known in music as “retrograde inversion,” which literally translates as “backwards and upside down.” The pitches of the motif are reversed in retrograde: the beginning pitch becomes the last pitch, and vice versa. The inversion of the prime series in reverse order from last pitch to first is a technique used in music, notably in the twelve-tone technique, when the inversion and retrograde procedures are done on the same tone row sequentially.
What is rudimentary form?
A stringent 12-tone work’s pitch content is fully (or almost all) generated from a single 12-tone row. The twelve pitch classes of the chromatic scale are arranged into rows. Order is crucial as each of the 12 will only appear once.
Transposition, inversion, and/or retrograde operations that connect two 12-tone rows are regarded as different variants of the same row. The 48 forms of a row are prime (P), inversion (I), retrograde (R), and retrograde inversion (RI), transposed to begin on each of the 12 pitch classes, unless a row has specific features that allow it to map onto itself when transposed, inverted, or retrograded.
Prime form
The primary form to which all other forms are referred is the prime form of the row. In some pieces, the texture will be obviously dominated by one type of row. If that’s not the case, pick the row that stands out the most at the start of the job and label it P. Flip a coin if more than one row first appears to be equally important. The choice of which to label “primary” depends on a single row form acting as a point of reference, but it is not necessarily crucial.
Any row form that is the same as that opening prime form or a precise transposition of it is also a prime form. Any following row that is an identical transposition of the row you classified as the main prime form at the beginning of the piece is prime. Similar to this, a prime form is any row that contains the same series of pitch-class intervals.
P can be transposed to any pitch-class level, thus we use subscripts to differentiate them. The numbering is determined by one of several widely used procedures. The easiest method, which we will use in this course, is to number the row according to the class of the starting pitch. A prime form is P7 if it starts on G(7) and P11 if it starts on B(11).
Retrograde form
A retrograde form of the row precisely reverses the pitch classes while taking a prime form. Therefore, its interval content is the opposite of the prime forms. The last pitch class in the row is indicated by a subscript after the word R for retrograde variants. In the event where two row forms are exact retrogrades of one another, this will guarantee that their subscripts match.
For instance, a row is R6 regardless of its first pitch if it has the precise reverse interval structure of the prime forms and terminates on F-sharp (6).
Inversion form
Inversion form is a row that precisely inverts the prime form’s interval structure (for instance, 3 semitones up becomes 3 semitones down or 9 semitones up, modulo 12). The initial pitch class of the row form serves as the basis for labeling inversion forms. I3 is an inversion-form row starting on E-flat (3).
The inversion procedure that generates this label is not always the same. (See the article on analyzing atonal music.) The inversion operation and the resulting row form will both have the same subscript if you start with P0. They will be different if not. Be careful not to mislead them.
Retrograde inversion
Similar to how retrograde (R) and prime (P) have a relationship, inversion (I) forms also have one (P). The last pitch class in the row form serves as the term for retrograde inversion forms, which invert the pitch classes of inversion forms.
An inversion of a melody is what?
A melody is said to be inverted when its ascending intervals are changed to descending ones and vice versa; for instance: becomes. The contrapuntal lines’ original placement is changed in inverted counterpoint.
What does music transpose mean?
A musical piece is transposed when the pitches are changed without disrupting the connections between the pitches (or notes). Transposition is frequently used in vocal music to account for different vocal ranges. Chances are that when we hum or sing a melody informally, we are not doing so in the key in which it was composed, but rather in a different key, unintentionally transposing the tune to fit the range of pitches that seem natural to our individual voices. Practically speaking, it is uncommon to transpose just one section of music while leaving the rest unaffected.
The Yankee Doodle melody has been faithfully reproduced in the sample, with the exception of its pitch level, which has been transposed up a minor third from C to E-flat. Transposition in this context equates to rewriting the melody in a different key. However, keep in mind that simple transposition never shifts a melody’s mode from a major to a minor note (remember, the intervallic relationships between the pitches do not change).
How is a retrograde inversion written in music?
List the prime form backward, beginning with the final pitch class and reading from right to left to obtain the retrograde. List the inversion form backwards while reading the notes from right to left to obtain the retrograde inversion.
What is music in fragments?
The use of fragments or the “division of a musical notion (gesture, motive, theme, etc.) into segments” is known as “fragmentation” in music composition. It is a typical strategy for localized growth and closure in both tonal and atonal music.
Fragmentation is connected to Arnold Schoenberg’s theory of liquidation, a composing strategy that describes the distillation of a complex musical theme to its most basic elements (such as a contour line, a specific harmonic motion, or the like). Many pieces of music with strong themes, such those by Schoenberg, Stravinsky, and Brahms, are shaped by liquidation. It’s crucial to realize that despite their similarities, fragmentation and liquidation are distinct procedures and ideas.
What distinguishes a 12-tone row?
Any note from the chromatic scale may be used as the starting note for each row form. The same pitch integers used in set theory will be employed here. We will utilize P and I along with an integer pitch to indicate the initial note for primes and inversions. P (text_), for instance, is a twelve-tone row beginning on C (pitch integer 0), P (text_), a twelve-tone row beginning on E, and so on. In the same way, row forms such as I(text_) (beginning on D), I(text_) (starting on F), and so on, also have the same problem.
How should a 12-tone piece be written?
How to Compose in Twelve Tone
- Start with a grid of 12 by 12. Label your grid as in the following illustration:
- The next step is to arrange the 12 chromatic pitches whichever you desire.
- Calculate your row’s inversion next.
- Transpose your 12-tone row into each key listed in the grid’s left column to complete it.
How can you recognize an inverted chord?
The top and bottom notes should be heard. Start paying attention to the note that is at the top (or bottom) of the chord for a more trustworthy approach. For instance, you can tell the chord is in the first inversion if you can hear that the chord’s root is at the top.
Has the child’s position been inverted?
While milder inversion positions assist the yogi in overcoming their anxiety of being upside down, more advanced inversion postures might be difficult.
Standing forward bend, child’s pose, downward-facing dog posture, dolphin stance, legs-up-the-wall pose, and shoulder stand are examples of basic inversions. Advanced inversions include headstand and its variations, scorpion posture, one-legged inverted staff pose, and handstand and its variations.
Performing inversion poses improves balance, strengthens the nerve system, flushes out toxins, boosts blood flow to the brain, enhances cognitive function, and relaxes the mind. It also reverses blood flow and promotes circulation.
