I know kurt is a fan of biggie, and I figure many of the other people on here are too, so I thought id point out an observation I had about Biggie- He plays over the bar! If you think about his verbal (musical) phrases being delineated by the rhyming syllables, Biggie, more than just about any other rapper, plays phrases over the bar and maybe even the "form" (4 bars, 16 bars whatever you want to call a rap "form" i guess). Not to mention his pretty damn sophisticated rhythmic vocabulary, and murderous improvisational skills... see 1:50 of http://www.youtube.com/watch?v=H-2I07UM_EA
When you think about it, rhymes are really just acoustic concepts and don't have to limited to words, and Im starting to think that there is alot of musical "rhyming" going on, where two or more "adjacent" phrases (ignoring phrasing ambiguity) are united by a common ending (maybe a similar gesture at the end of each, or a similar interval, or something less concrete). Can't say exactly what does it, but I hear some lines and I think they rhyme... anyone else kind get what I'm talking about or experience it? First guy that comes to mind is keith jarret, like some of his mid tempo stuff with the trio. Certainly heard Kurt do it too. Im aware this concept sounds totally unclear still, but im hoping someone will just be like "yea man, i know EXACTLY what you mean!"...
