Im a band director from Texas and at a recent marching contest the percussion judge said the snare drums sounded to "OPEN"...Im a brass guy and dont have a percussionist on staff so I was hoping I could get some help here on what this means and how to fix it. He suggested I look to tuning the snares diffrent so they wouldnt sound so open. If you could help me out I would really appreciate it!
