These packets can be used at your own pace to help teach all  of the Chromatic tones and their enharmonic equivalents in a roughly standard band instrument range (Bb3-F5). 

Each section introduces only one new pitch and then adds it to previously learned notes in chromatic succession with various patterns and repetitions. When I use this with my younger band students, I choose to focus on one section per week to properly reinforce the new note properly, but it is up to you how fast you want to move depending on the needs of your own ensemble. Have fun with it!
