I have been practicing my scales and at times chord changes with the metronome. I think it helps with keeping time, speed. Can anyone fill me in on the true benifit? Is timing and speed it? Is this a good practice tool? Also how much time to put in practicing per day. I put in 1 Hard Work hour per day. After that its play time when I still have it in me. This reasonable more or less? I would be thankful for thoughts on this and/or tipps that will help me become a guitar player someday, ha ha. Anyway Thank You.
