I've been working on my solos, trying to make them more sophisticated, and I've fallen into composing over the changes to So What, which I find works well for this because it's simple enough to force me to focus more on the melody than the changes, but the two changes gives me something to aim for. Because of my studies, I've been once again pondering the differences between a solo and a composed melody. And, yes, I did a search and went through the first page of results but didn't find anything on point, plus, I reason that if it's been a while since the last time this question was asked, there are different folks here now, so... but, if you're better with the search engine than me, or can point me to the previous discussion, I'll appreciate it. I think you can argue that a solo is just a spontaneously composed melody and in many cases that is correct. Certainly, back in the swing days of jazz it was, what, mostly true? but, solos moved away from just simple melodies back in the late 30s and now there's a lot more technical and harmonic pyrotechnics than Louie played. Additionally, a solo usually spans more than a single chorus and the melody isn't usually recognizable between the choruses of the solo, so, they're fundamentally not the same even if that's your approach. In many ways, I think a modern jazz solo is more like the movements of a symphony, about contrasts leading to a series of climaxes with the most emotionally charged climax about 2/3s or 3/4s of the way through the last chorus, when the solo trails off to set the stage for the next event. the head or the next soloist. I've been focusing on building the climaxes between the choruses, making the last climax the most dramatic and I'm getting a handle of the different devices I can use but I thought I'd ask the hive-mind for comment. What say you?
