The books I use in band are Standards of Excellence and in orchestra is All for Strings. I constantly modify what I give extra to my students and what is learned in the book. I started out going one after the other, but quickly found it boring the students and I was bored. I believe in students choosing their instrument for a reason. It's our jobs to keep that flame alive in the student and expose them to music they will be motivated to learn. Motivation is a FABULOUS tool to teach them the technics they need to learn and master. For example: I give students music they would be familiar with from shows, radio, cartoons, movies, etc. as a side fun thing for them to practice. I try to connect what they learn from their books and sheet music to music they know, culture, and bring technology in the classroom to give them further exploration in music.
