We can apply this to guitar playing or life in general but is there anything that stands out to you as something that you really wish you knew before ?
Talking about guitar / music, I think one of the hardest things to learn (that's if you even want to) is to let go of following what other people do and trying out your own ideas with the ultimate goal of finding YOU through the instrument.
I've touched upon this in another old post; One of the things that holds us back from trying out ideas that are 'unproven' is a fear that we may waste time on something that may not even work. So the lure back to working on 'proven' licks is too tempting to ignore. But what if there was no actual categorical need to be able to play certain licks ? What if there was nobody saying that you've got to have a specific type of lick down ? What if the door was blown wide open and you could just explore (without any guilt or doubt) any sounds that take your fancy ? It could be something that is just the seed of an idea in your head but you might have an inkling of a particular sound, style or phrase in your mind but you haven't managed to make it real yet.
A great quote from Jimi Hendrix reinforces one of the most satisfying goals of playing a musical instrument:
"My own thing is in my head. I hear sounds and if I don't get them together nobody else will."
I think that quote encapsulates the musicians 'burden' perfectly. How many player out there truly dig deep and unearth something that doesn't sound like something already out there ? It's hard because the repertoire of established guitar techniques is pretty much universal so we all use them. It's not easy to get our own sound out but I kind of feel that it is a noble duty of ours that we can choose to take on if we are so inclined.
A lot of you have already talked about the idea of listening to other instruments and / or vocalists and emulating them for inspiration. That can force one to find a new way of negotiating a phrase. Before you might have played a typical linear guitar line but now you may be faced with a lick that is played on a violin tuned in fifths. So you fingers may have to travel unfamiliar paths. Not only that but the inflections of a different instrument may inspire you to use your bending skill and vibrato in ways you'd never thought of before.
That's without touching upon the tonal possibilities or if you have a whammy bar.... we're just scratching the surface but that's how we start playing outside the box.. the box that we put ourselves in. But we can't blame ourselves. As humans we hear, we see, we do. Mostly. So what if we take that away ?
Pretend you've never seen or heard another guitar player. You've got this electric guitar thingy. It make noise. What sort of noise would you make with it ?
There is a balance, as always. I think it's necessary to learn a lot of foundational skills that are vital to playing with other musicians, in a band, or getting work in some way... but to balance that out with enough time spent in 'discovery' mode is the ideal goal, I think.
But I wish I knew this stuff years ago. I would have started concentrating less on playing what I have heard and concentrated more on what I haven't !
So, what about you ? The above subject could warrant much discussion as it is but you can apply the question to any aspect of life. What do you wish you had known years ago ?
