The method we have found most powerful for eliciting knowledge is to use stories. If you ask experts what makes them so good, they are likely to give general answers that do not reveal much. But if you can get them to tell you about tough cases, nonroutine events where their skills made the difference, they you have a pathway into their perspective, into the way they are seeing the world (p. 189).
Practicing and performing and gigging are problem solving. How do you work out that touch section? How do you get over stage fright? How do you organize a concert program? How do you book gigs?
Klein is right that the best way elicit knowledge is through stories. Every time I write a post on The Classical Guitar Blog, I’m telling a story about what has worked for me. Or I’m telling you a story about what I do in the practice room or on stage. These are authentic stories I live every time I sit down with the guitar. Your teacher has just as many stories and just as much knowledge.
So ask for those stories. Ask your teacher what she did the first time she performed. Ask him how he practiced that difficult bit in a piece, even if it’s not a piece you’re working on the lessons in those stories can often be applied to other works. Ask about their early years or playing and what they did to get better during them. You’ll be amazed at the responses you get.
