Accompaniment Band Method Books
You might, for instance, be looking for an instrument-specific companion for your resources. In that case, something like the Alfred Sound Innovations for Concert Band Book 2 Piano Accompaniment Book could be the way to go. It's designed to pick up where the base book left off, introducing more advanced concepts in segmented steps that makes them easier to understand. It's an invaluable resource for intermediate piano students, and it's just one example of what you'll find here. Another piano book, the Hal Leonard Essential Elements 2000 for Band - Piano Accompaniment Book 1, has earned itself a well-deserved ranking as one of the best sellers in the section.
If you're looking for a more engaging, interactive type of accompaniment band method book, keep your eyes peeled for ones that include CDs. The KJOS Standard of Excellence Book 1 and Book 2 Accompaniment CDs are great examples; in fact, each of those is actually a 2-CD set, offering up a wide variety of professionally-produced recordings to go with each level in the popular KJOS Standard of Excellence Series. For musicians who learn by doing, there's no better accompaniment than these.
Don't wait to stock up on accompaniment band method books. Whether you're expanding an already-diverse library of method books and reference materials or building up a new one from scratch, there's definitely room for these expansions to make it as in-depth as it can be. The results will speak for themselves when you're working with a band whose members have access to all the accompaniment resources they need to take their performances to the next level.
