We're all familiar with the concept of lyrical rhymes. For example, the words through, curfew and blue all rhyme despite being spelled differently because the sound of their final syllable is the same.
But if you're analyzing instrumental, i.e. non-verbal music, does it make sense to say that two musical phrases rhyme?
Consider the opening of Beethoven's Fifth Symphony:
Could you say the second four-note phrase rhymes with the first? If we can agree that rhyme is a helpful musical term, what might the rules be? For instance, in the Beethoven example, if the second phrase ended with a leap up to a D rather than down to a D, would that still be a rhyme?
Or is rhyme too vague and ill-specified to be useful as a term of musical analysis?
BTW, I did try googling for this but got lots of hits related to songs for small children, rather than technical terminology for musical analysis.
