John Scalzi asks an important question: is Spinal Tap a real rock band? He adds a follow up, whether the band is worthy to be in the Rock & Roll Hall of Fame. The first one is an interesting question, which can be generalized to all musicians: what makes a musician real? Is it the technique, the musicality, the authentic desire? If reality is based one or more of these qualities, at what level does a person become a real musician? A beginning violinist can only play "Twinkle Twinkle," is that person a real musician? What about when they finish the first Suzuki book?
As my own follow up, can you think of any classical music equivalents to Spinal Tap? Victor Borge and PDQ Bach are the two that I can think up.
