I'm always interested in what both the pros as well as the rest of us do in keeping sharp across multiple instruments. I play soprano, alto and tenor saxes, along with clarinet and flute. A high-quality community band is keeping my clarinet chops in shape, and my contemporary praise band at church along with our local community jazz band keeps me going with the saxes. The flute? Well...currently it's getting neglected. I find rotating the saxes in practice sessions keeps all 3 going. Currently using the Voxman Selected Studies and the Kynaston Daily Exercises along with a Real Book for jazz. For clarinet the Rose and Klose studies, an old copy of the Albert Scales and the community band music on weekends and the night before rehearsals. When I have to get the flute ready for something, I love the Galway tone exercises and scale work. I really love it when I can get an hour on any of them in a single day. But my 40+ hour a week job as a database analyst/developer and being a husband, father and home owner prevent much more. How about the rest of you?
