As mentioned in the topic Learning to play jazz guitar I bought a Burny RFA-75 archtop from Richard's Guitars and a copy of Mark LeVine's The Jazz Theory Book with the intention of learning jazz guitar. I reckon this book will keep me going at an enjoyable and leisurely pace for a few years.
Okay, first conversation topic: on page 4 it says, "If you can sing an interval accurately, you'll find that the interval is easier to hear when you play it." This has been my weak spot throughout the 40+ years I have been playing guitar and so I want to work on this. A friend tells me that Mozart could not sing, he just heard everything in his head. I suspect that Mozart could have sung intervals accurately. Can you? Should (jazz) guitarists be able to sing and recognise intervals accurately?
