Reddit reviews Noble Snare

Not sure what your skill level is, but check out the books by John S. Pratt and Charlie Wilcoxen (sp?). Pratt's stuff is very military-esque. Morris Goldenberg's "Modern Approach for the Snare Drum" has some great exercises as well. In college, my prof would have me do the simple duets as a solo. Top line with the right and bottom with the left. Additionally Al Payson's "Snare Drum for the Concert Hall" is another great resource for tightening the screws on your chops. For more advanced concepts in the Marching realm, Jeff Queen's book is my go-to text.

Sorry for the lack of links though. I'm on my phone. If any more come to mind, I'll edit this comment. Interested in seeing what other books/pieces people recommend. Happy shedding.

Edit: Someone recommended the Noble Snare books. It's a great collection of "out-of-the-box" pieces from numerous notable composers. If that's your bag, check out Askell Masson's snare solo entitled "Prim". It's a bitch to learn but a blast to play.

Edit 2: Got to my computer and retrieved links for all my suggestions. Who loves ya baby?
