Type I refers to a jam that stays within a song's melody, rhythmic structure, key, etc. Think of songs like "The Mango Song" or "Funky Bitch." The instrumental sections of these songs almost always sound like the same song - in other words, Type I.

Type II refers to jams the deviate beyond the song's structure, key, melody, etc, and into more free form improvisation. Songs which often have Type II jams include "Piper", "Tweezer", and "Ghost."

Also, thanks to those above who noted the excellent "Tela" on 8/27/88 and also pointed out some obvious typos on my part.
