Each committee will select a set number of qualified alternates for each section of each band. Alternates may attend the Region or All-State Clinics at the discretion of their directors. Alternates attending the clinics will not rehearse with their respective bands unless they are needed to fill a vacancy. In all other respects they are considered actual members of their respective bands and may receive medals, provided they attend the clinic. No student who scores less than a total of 75 points on the region audition will not be allowed to participate in the Region Honor Bands or Alternate Band.
