Check out this article with good ideas for parents on how to give support in learning a musical instrument to your kids. Beginning band students need to have correct posture, breathing, hand position, and embouchure to give a strong foundation for learning to play notes on the instrument. Regular practice in playing long tones on their instrument is a good starting place for practice. Students are also given warm ups to play once they are secure in their beginning notes. Please have your student practice 10 minutes a night on their instrument to help develop these skills as beginners.
