Just because you’re holding your guitar doesn’t mean that you’re playing it, and just because you’re playing your guitar doesn’t mean that you’re practicing. There is a real difference and it needs to be acknowledged if you want to improve your level of playing skill. Some people say they have spent entire day practicing their guitar when in reality, all they’ve done was sit in front of TV all day eating cheesy poofs. The sad thing is that they really do believe it was practicing since they had their guitar on their lap next to their cheesy poofs all day. Most of us know someone who does this and we may even be guilty ourselves.In order to truly improve your skills you really need to avoid any distractions, no TV, no food, no friends and no phone. Just you, a guitar, an amp and maybe some reference materials. Speaking of amps, keep distortion turned down. Remember, this is practice, not playing. The distortion will only hide your mistakes. You need to hear your mistakes clearly so you can correct them.
If you’re a beginner you might want to practice basic guitar scales or guitar chords. Make sure you have necessary reference material handy so you don’t spend your time doing things wrong. Keep in mind that what you practice is reinforced so if you’re practicing your scales wrong, then you’ve not only wasted your time; you’ve also reinforced your mistakes.
So what should you practice? Since I’ve never heard you play I can’t tell you what you need to improve on, but I can make suggestions to make your practice more effective.
Don’t turn your amp up to 11 and play every solo you know. This is playing guitar not practicing guitar. It might be fun and a great way to blow off some steam, but it won’t improve your skills.
Don’t let practice get stale. You need a variety of things to keep your mind from wondering. Practice your scales for an hour then work on chords or music theory. Mix it up. Just be sure not to over do any one area because you’ll get bored and at that point your practice won’t be as effective.
