I have to describe short melodies composed by beginner students. They are typically just a few bars long, and are composed bar by bar, so most of the times there is a 1-to-1 correspondence between bar and motif -- although this is not always the case, I'm just pointing out that they typically are just very short motives. If I choose to represent a melody of four motives like (for example) A, B, A', C (that is: A, B, and C are distinct motives and A' is a variation of A), what is the name of this representation? My advisor called it "motivic analysis notation" but I cannot find a source to confirm this. I'd also rather not call it "thematic analysis" because I have used the term elsewhere with another purpose.
I haven't done proper music studies myself, but I will have to defend that against a musician, so I'd like to use the proper name.
