Classroom culture in band starts from the beginning, usually 6th grade when the students first learn about band. From 6th grade up until they stop playing, from one year to fifty years, musicians do things the same way all the time. We are creatures of habit.
Students are held to a very high standard and they have to work at it, some more than others. But, the foundation is; you have to work at it, practice many times, to achieve your goals. It is good to make mistakes while we are still learning, that is how we fix things. But, the end result should be as close to perfection as we can, the final performance.
We talk to our students everyday about using these tools in all areas of their lives, education, family, work, and wherever they may need it.
