No no, I'm sorry if you took it that way, I'm not calling you stupid or less of a musician or anything like that- of course not. I'm just speaking from personal experience, from what I've seen in person and what I've seen on YouTube. And of course you should have the technicality required to play your solo before you play it, that's stupid to try and play something you're incapable of. I don't know if we all hate Yngwie here since it's America so we're probably all Satriani-fanboys, but I know even he says that "If you can't play it clean as well as fast, don't play it at all."
I think even more than rhythm, the melody of your solo is more important, since the term melody entails both rhythm as well as pitch. I'm not sure what you mean by "using it to your advantage", but that sounds to be in the same vein as guitarists telling me that I'm stupid when I bash their solos because "That lick was made to catch your attention," or "That lick's based around the fifth to fit the Cmaj7#9." This dude was pulling shit like this out of his ass for ages when I told him his composing and improv skills sucked (http://www.youtube.com/watch?v=LmbZxQQJWJg).
Thinking so much before you play makes you sound so mechanical- you can describe it as amazingly as you want but if it doesn't sound good in action, what's the point? Plus, if a "fifth" sounds best during a "Cmaj7#9" chord, I'd rather be the type to recognize that by hearing and to match a great sounding lick to that chord without having to listen to the song 10 times beforehand to write a lick that sounds decent. It makes your playing much more organic and expressive, I think.
Tensai, if you have a videocamera, would you mind recording some of your playing for me as I'm very interested in how you play, unless you have some videos up on YouTube already? Plus, I don't think there's a such thing as "practicing properly". Yngwie J. Malmsteen never once practiced to a metronome, but look at how clean his playing was when he was with Steeler.
And this is sort of relevant, Tensai. Could you tell me what you think of this?
