I've been playing for about 5 months now, starting at the beginning of June. Ever since, I've been practicing rigorously, an hour a day. However, I feel like for the past 2 or 3 months, I've hit a wall. It's not normal to hit "the wall" so early in instrument playing. I consider myself VERY sloppy. I can play some difficult songs, like the main riff in YYZ and Lounge Act, but not cleanly. Even simpler riffs I have trouble playing with good time or consistency. If anything, I'm getting worse. What do I do? There must be something inefficient about my practicing. My definition of practice means sitting down for and hour and playing some riffs or trying to figure out new ones. I'm somewhat well-versed in theory, it's my technique that's bothering me big time. Any advice?
