Jazz Trumpet Technique - Vol 2 - Tonguing
How many hours do you spend working on the same mindless tonguing exercises, flexibility exercises, and chromatics? By adding harmonic awareness to the exercises, you can exercise your ears, mind, and chops simultaneously. Imagine how productive you will become. Every trumpet player knows the importance of practicing tonguing. The exercises in this book should supplement (not replace) the amount of material practiced.
I suggest that you start by spending 25% of the time you would normally spend on traditional tonguing exercises on material in this book. Then increase the percentage (up to 75%) as your chops adjust to this new routine.
