Sweep picking is one of the most coveted techniques on the guitar and has become surrounded with myth and legend. While it's true that it takes real dedication and a good deal of practice to completely master sweep picking, it's nowhere near as difficult to learn when you know the secrets behind it.
Imagine you're at a large gathering of people waiting for a band to come in and perform. The band cancels at the last minute leaving everyone disappointed and bored. The gathering needs some live music and you're the only person there who can play the guitar. An acoustic guitar is available but you have no songs ready and nothing prepared. Would you be able to entertain the audience and keep them engaged for an hour without preparations, without a repertoire, and nothing but an acoustic guitar?
Winning isn’t everything, but it sure is important. How many times have you had a “winning experience” at some point in the day and felt negative afterword? Seldom. What we do as guitar players to improve can be a slow, gradual move forward. For example, today I can play this at 79 bpm when yesterday it was 78 bpm. Progress? No doubt. But it doesn’t really feel like winning does it?
From the beginner or intermediate standpoint, becoming a master seems like an impossible goal. As I've said on a few occasions, this is because it would take many lifetimes to achieve mastery if your progress continued at the same rate as it does when you first start out. However, since we know there are masters of the guitar, we can easily deduce that the rate of progress actually increases exponentially over time.
Practice method is one of the most critical aspects of mastering any instrument and, while people are reminded to practice often, there is never enough emphasis put on optimal practice technique. People tell you to practice but what they don't tell you is that if you aren't practicing correctly, practice can get you nothing but years of frustration.
