Reddit mentions of Bop Duets Complete Including Vol. I-II-III

Depending on your playing ability, this book may be acceptable if you prepared your lines ahead of time. I use it with my teacher for sight reading but I played lead alto in my school system's honors jazz band, so I'm certainly not new to jazz. I have friends who aren't at the same level I am and I really like playing the duets with them when they practice ahead of time and we can just play. The lines are really interesting but it might be a bit too high level. If you do get it, go to the middle of the book first. The front is the hardest and the back is pretty dumb. The first 2/3 is all really good, but the most manageable stuff is smack in the middle. I can give you a pretty definitive answer if you give me something more to work with like what book you're in, how long you've been playing, your experience, etc.

Seems like you're a very "legit" player (I hate that term). But, if you want to expand to jazz, these Bop Duet books are stellar! http://www.amazon.com/Duets-Complete-Including-Vol-I-II-III/dp/B001ANVT10

If you want to learn trumpet make sure to practice scales and memorize them. Get a manuscript book to jot down your regular warm ups, you will need them. For jazz this book is awesome for not just you, but any jazz group you join. It has awesome songs that are perfect for messing around with.
