I have heard of this approach and I think it works. We do need to push ourselves in order to make progress. If we try to play a tempo that is too fast for us, practicing some time on it and then going back should almost always have a positive effect and make the previous tempo feel "slower". Downside with this (and with almost any metronome practice) that we sometimes tend not to be self objective. Meaning that we shouldn't skip tempos and try to achieve speed while playing sloppy/not in time etc. Sometimes its easy to fool yourself into thinking that you "mastered" the certain tempo and going forward as that only develops "sloppy" playing further.
That being said, I think we should always challenge ourselves with this "slightly faster" tempo method in order to be able to comprehend the previous "slow" one
There is nothing wrong in trying to play something out of your reach. Hell - I think there should be no limits in any kind of practice. If you just picked up guitar but you would like to play sweeping - go for it, there is really no reason why you shouldn't do it!
Good thing is that everyone can learn any technique at ANY stage (skill) of playing guitar. Just slow down the tempo to something reachable and push forward.
Well said Bogdan
yes I do this as well, The trick being if you are above your speed to much , you will teach yourself to be sloppy.
So , once you push your speed , always back down to perfection
I really like this idea.Its great to know other people use it. Do you think it is quite popular for guitarists because I have never really heard people talking about it
