Young instrumentalists are taught to press buttons or keys to make pitches sound from their instruments, but that doesn't always ensure that they are in the center of the pitch. It also doesn't ensure that they are in tune with those around them. It is important to improve awareness that pitch is not only physical, but conceptual as well. It is important that instrumentalists know how to center pitch and make adjustments while playing their individual instruments, to compensate for tendencies of said instrument. There are many ways to practice this. I met with four flutists three times to try to help them with this process. They sang, used tuners, and created a journal. All of this helped increase awareness of playing in tune. In the end, they found out what adjustments they needed to make individually to get the pitch closer to the center.
