What is retrograde 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." Retrograde reverses the order of the motif's pitches: what was the first pitch becomes the last, and vice versa.
What music is retrograde?
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.
How do you write a retrograde?
Write the retrograde by reversing the order of the pitch class numbers. Write the retrograde-inversion by reversing the order of pitch class numbers in the inversion. The reference pitch of the original and inversion forms is always the first note.
