Beginning band can be a cluster chord for the first few months. Have you ever said, "Do you hear that wrong note?" What's a band director to do?
Ear training is the foundation of error detection: teaching your students what these notes are supposed to sound like. When exercises in ear training are implemented into the middle school band room, students learn not only the pitches but to: audiate, sing and play in tune, and intervals.
I will be uploading these files individually by instrument so you can buy what your band needs. Go measure by measure, line by line, or the whole page to implement daily ear training into your instrumental band program!
