DrumGod, my ex was at Southwest from summer '93 to fall '96. He mostly took summer and night classes and specialized in Kodaly as he is an elementary music teacher. Southwest actually has a very good Kodaly program.
Anyway, I would call Beethoveen’s 5th symphony’s rhythmic idea (ba ba ba bum) a theme as it is used so pervasively. If it was a motif I would usually think it would only stick in one movement and maybe repeated in the finale. This one is rather tricky as it can be looked at either way, but that is how I would analyze it.
I still have my Analysis and Synthesis and Musical Styles books somewhere at home. I know one of them had some discussion of Beethoveen’s Fifth in them somewhere. I will double check and post next week.
You are still well versed in music DrumGod. You will do well. You are right, Bach used his BACH motif (you are right it really isn’t a theme although I said that earlier) with all the notes in succession. I always thought of it as an early chromaticism that formed the melodic minor descending scale (in C) but I haven’t ever researched it to find out for sure so it is all up to speculation as to when the melodic minor really came into effect.
HUGS!
