English.
From the Foreword, by Allan Dean: These wonderful exercises and comments are centered on the idea of raising the daily warmup starting point to third space C or higher, to fourth space E or fifth line F. The exercises cover many areas, giving the player options to choose while focusing on this higher starting point. As always Chris' comments are thoughtful and practical in approaching the trumpet. I have been doing these exercises daily since I received them several weeks ago from Chris. Even after all these years of trumpet playing, I have found that raising my centre up to E and immediately expanding higher has been surprisingly comfortable and beneficial.
