The Scholastic Band Lesson Curriculum gives you a complete lesson curriculum from Elementary (instruments out of the wrapper) through Secondary. The lesson curriculum is designed for group or individual lessons. This is designed to "plug up" the holes of the non-homogenous texts. There are instrument specific diatonics that deal with the individual issues that are often omitted in the non-homogenous texts such as clarinet break, flute octave development, brass lip flexibility to name a few.
