I Play the Guitar

It is an elementary piece. I suggest taking each bar at a time and slowly working through it. I try each bar 5 times then move forward playing the next bar 5 times and then put them together. I believe getting a repertoire of say 5 pieces and working them to a good standard is better than rushing. Try 5 pieces with different demands eg keys , timing or techniques. Lessons are best but the books by Noad are good.
