Zlet's say "paraphrasing" in music as an analogy of paraphrasing in psychology and psychiatry? or in other words: how much reputation will I need to determine or define a term? will 40k fit for it? how many doctor titles do I need? how many books must I have written?
The term paraphrase seems quite clearly defined. Right coming from searching another term for the fill-ins, echo-ing, answering in the dialog of 2 instruments, singer and piano or guitar, I proposed the term "paraphrasing". Now I've found paraphrasing used in of other answers and comments. I don't think that there is evidence of it. If yes, thank you for answering.
