Great, another anti-shred thread.
Whoever said something about how a note held for three seconds can touch someone's soul, and that's the point of being a guitarist... Yes and no. I agree that the reason we all play guitar, if you exclude factors like "free beer" and "chicks dig guitarists," is to move listeners. At the end of the day, how good a solo is can't be measured by counting the number of notes played or measuring bpm, it's totally a factor of how effectively the guitarist managed to make you
feel something when you hear him.
But, you know, that cuts both ways. If it's not about the note count, then playing fewer notes doesn't automatically make a solo better either, and you can't simply make blanket statements like "to move people, you need to hold a note for three seconds." That's simply not true - there are so many factors in play here it's not even funny. I could record a solo where I hold one note for ten seconds, and it'd sound like absolute crap, you know? Play something out of key, bend it slightly further off, and then bust out your best Kirk Hammet vibrato, and it's going to be almost painful to listen to. True, technically, you're making your listener "feel" something, but I think you and I both agree we're not talking about agony when we're talking about feelings.
So, what's the secret, then? Really, I guess, there isn't one, or rather there isn't "one." there's as many different ways to make your listener believe in you as there are guitarists, good ones anyhow, and a large part of finding your style and your voice as a player is finding one that works for you. I can give you a few things to think about that I've found valuable over the years, but really from that point out it's trial and error. So...
1.) work on your vibrato. Very few excellent melodic soloists have bad vibratos. Actually, scratch that - I can't think of a single melodic player worth his salt who's vibrato isn't at least OK. I'm not really blown away with Gilmour's, strangely (it's a little narrow and fast for me), but even then it's perfectly serviceable. Vibrato is sort of an after-thought for a lot of players, and really it shouldn't be.
2.) On the most fundamental level, music is entirely about tension and release. don't think of your solos in terms of the notes you're playing, but rather in the terms of how you're building or letting out tension. Look at this in a number of layers; how you want the tension to build (or alternatively not build) over the course of a solo, how you want to use tension to build movement over a particular set of chord changes, over a bar, over a measure, whatever. Also, think in terms of rhythmic tension (on the beat vs. off the beat), melodic tension (how's your chord theory and harmony? spending some time working out how different chords resolve into each other can be a VERY fruitful process), and, yes, technical tension (varying up fast notes and slow notes, etc). Those "three second sustained notes" CAN be pretty dramatic... but that's not because they're long and drawn out as such, but rather how the player builds into it.
3.) Work on your bending. Another no brainer, maybe, but a bend is a lot more than just a way to smoothly get from one pitch to another. One of my favorite solos in this respect is Albert King's "Personal Manager." In the main solo, there's a chorus where he simply plays one bent note over and over again, but each time he plays it it sounds different- sometimes he plays the pitch and bends up, sometimes he prebends and releases, sometimes he prebends and holds it, sometimes when he bends up he bends most of the way up very quickly and then slooooly eases up to pitch for the last few fractions of a step, sometimes he bends really slowly at first and then quicjkly jumps up to pitch right at the very end, sometimes he stays a little flat, sometimes he doesn't, et cetera. Track down a recording (I've got a compilation of his called "King of the Blues Guitar" that is pretty excellent listening), and then listen to that solo while thinking about how he's bending and about how he attacks each note. Then, pick up your guitar and try to recreate it. It's really a total technical tour de force, even if it's just a series of 8th notes.
I remember this jazz player I studied under during college, a guy named Paul Asbell. Great player, and a great teacher too. Right around the time Satriani's "Engines of Creation" came out we were talking about the album (he knew I was a huge Satriani fan), and I mentioned that the solo on "Until We Say Goodbye" was one of the best lead breaks I'd ever heard. He kind of chuckled and asked me to bring a copy in for him. The next time we met up we talked about it for a while, and he said something that kind of stuck with me that I'll paraphrase.
"The thing with guys like B.B. King, is they have this thing where they hit "that one perfect note," and it sounds great, but that's also
all they can do. That's not a bad thing, it's just who they are as guitarists. I think it means something a little different when a guy like Satriani does it, because you know unlike King he's capable of blazing through 32nd notes all night long. When he does it, it's a conscious choice."
I thought that was a very interesting observation that I've thought a lot about in the years since. And, I think there's a lot of truth in that; to this day my favorite solos aren't the ones where it's just blazing legato run after blazing legato run, or a handful of slow notes, but generally they're solos that combine a good degree of technical aptitude with a great ear for melody. I personally think that THAT is the point of technique - to serve the melody and to make the melody that much more dramatic through contrast.
Food for thought...
PS - buy "The Wall." Listen to it on repeat for the next two months, give or take. Rent the movie, while you're at it. I'm not saying that's the only way to learn how to play interesting solos without relying on heavy technique, but it certainly can't hurt.
