GavestonPS said: "Oddly enough, my college advisor told me the exact OPPOSITE of the advice attributed to Pat Pattison above. My advisor told me to take out some of the perfect rhymes and put in imperfect rhymes instead in order to LOWER the tension of everyone singing with such precise diction.
If what Pattison is reported to have said is true, why bother with slant rhymes? Why not use identities (as Hammerstein did in his work with Rodgers) or simply not rhyme at all?"
Obviously, impressions of art and terms like "tension" are highly subjective, and I can't know whether what your professor meant by that word and what Pattison meant (and what you or I mean by it) is the same, any more than I can know whether we all see the same color when we think of "red." That said, here is Pattison's taxonomy of rhyme based on my notes from the course:
Perfect Rhyme: most stable, identical vowel sounds and same consonant (if any) after vowel; must have a different initial sound so as not to be an identity; fully resolved (e.g., fight/kite, abrupt/corrupt, cry/try)
Family Rhyme: same vowel sound, but consonant rhymes created within same phonetic category rather than identical sound; i.e., plosives (p, t, k, b, d, g) with other plosives, fricatives (v, TH/th, z, zh, f, s, sh, ch) with other fricatives, nasals (m, n, ng) with other nasals; such rhyme can still create closure, but with acceleration and a tiny bit more flexibility and instability compared to perfect rhyme (e.g., grim/grin, hymn/thin, height/pike); voiced vs. unvoiced can also vary in stability (e.g., brig/brick vs. twig/lid; voiced -> unvoiced consonant creates more closure vs. other way around; family rhymes within same voiced/unvoiced category are also more stable than mixed between the two)
Additive/Subtractive Rhyme: when dealing with words that don't end in a sound that is in the same phonetic family or in a vowel, we can use an additive/subtractive rhyme; add/subtract as little as possible to keep stable; the addition of a sound makes it slightly more stable, while subtraction creates instability (e.g., Brit/grits, cry/bride)
Assonant Rhyme: always unstable; only the vowel sound is the same (e.g., cat/bag, light/knife, feed/theme)
Consonant Rhyme: most unstable; vowel sounds are different, but the final consonant is the same (e.g., friend/mind, sent/grunt, grace/twice)
So, Pattison's take on rhyme was a lot more nuanced that I had originally remembered (I took the course in 2013, so it's been a while), and he uses the term "stability" rather than "tension." To my ear, his hierarchy of stability/instability seems basically correct but, again, it's obviously going to be very subjective and dependent on context.
