At the beginning of the year I decided to focus on picking technique, someone here (sorry don't recall who...but thanks!) posted a link to Troy's site and I quickly went through all of the content. Some people want to know what time it is...While others want to know how the watch works....I'm the latter and Troy's site was eye opening. As said earlier, it's obvious in retrospect...but not exactly intuitive. Troys explanation of the mechanical efficiency made perfect sense, so I was determined to switch to one way pick slanting exclusively (combined with the string switching rules) it was unnatural and slow at first, but after a week or so with metronome at very slow rates..it clicked. The moment it clicked was just as troy described his experience...suddenly things I could never hope to play at speed were within my reach and my outlook on the instrument changed completely. Then after a couple of weeks working on the mechanics, I discovered Claus Levin's youtube channel...That guy is on another level and I'm not talking about his picking technique (amazing as it is). His ability to convey info (and motivate) was exactly what I needed. Troy got me to understand the mechanics and Claus filled in what Troy doesn't go into...How to practice them. Between the two of them, it has changed everything for me. Clearly, there is no "one way" and what works for some does not for others as evidenced by the great players with varying technique. But I can say unequivocally, that it made a enormous difference for me, I only wish I had learned this years ago.
