Atonal Etudes

If there is one thing that has helped me with my sense of pitch and interval with horn, it has been atonal etudes. The etude books of Gunther Schuller, Charles Decker, Falk, and Cheynes (the last two are part of that whole French scene of etude books). Even some solos, like those of Alec Wilder, are exploratory enough to through your ear for a loop.

The Decker book is devoted to 12-tone work and is technically the easiest. Each etude is based on a row which is display at the top. The Schuller etudes are more pattern-and-variation based (my personal favorite). They are somwhat Kopprasch-like in this respect, but much more interesting and fun! The Falk and Cheynes are quite tough and require a lot of work.

If you ever want to explore new and interesting ground in your non-solo work, give these books a shot!
