1 the act of prolonging something; "there was an indefinite prolongation of the peace talks" [syn: protraction, perpetuation, lengthening]
2 amount or degree or range to which something extends; "the wire has an extension of 50 feet" [syn: extension, lengthiness]
In music, especially Schenkerian analysis, a prolongation creates the detail of a musical composition by elaborating the background structure. Prolongations include diminutions. A coda is a passage which brings a movement or piece to a conclusion through prolongation.
