Hi All,

Was not sure where to post this question...but here goes.

Background first:

Been a GT member for 1 year. Worked thru Fundementals, Rock Level 1 and now working thru Blues Level 1. I practice 1-2 hours a day and overall happy with GT and my progress.

Recently I decided to spend more time learning songs and riffs, as opposed to exercises etc.

One thing I am noticing lately is that my best playing when learning and practicing riff is within the first 5-10 min of my practice session...in terms of speed and accuracy. For example i have been working on the verse riff and chorus to Back in Black and trying to play them clean at 92bpm. I have it when I first pick up the guitar, tjen after 10 min or i start making more mistakes...and the more I slow it down and concentrate after 10-15min tje worse i play.

Almost feels like if i just pickup the guitar and dont think much about it i can play clean...but once i think about it my playing degrades.

Any thoughts or advice?
