Anyone use this book, or know anything about it, and would like to comment on it? I don't know anything about it myself other than it exists, and John Goldsby plays with intonation I like from listening to the Amazon album excerpts. I'd like to hear him do fewer opposite bows on his Cupbearers solo, and instead do more slurs to mix it up a little, but my criticism isn't meant to mean that he doesn't sound fabulous, or that a jazz bowing stye of some kind he may be presenting there isn't "legit" and needs to be disrespected. If I was improvising something, you bet I'd be doing opposite bows through my entire panic solo. I'm used to a lot of pre-planning with bowings to address issues, and am wondering if this book offers valuable insights on bowing improvised lines.
