Welcome, Interlake Orchestra Students and Families!

We are excited about this year and all of the fun things that are going to happen! Interlake Orchestra consists of three ensembles: Concert Orchestra (freshmen and first-year orchestra students), Sinfonia Orchestra (non-audition 10th-12th graders), and Chamber Orchestra (audition 10th-12th graders).

Interlake Orchestra uses CHARMS as its primary method of communication with families and students. Make sure to register with CHARMS using the instructions below in order to receive emails for news, announcements, and information. We will be updating this page all year long with news, information, photos, and videos from this year’s events and performances.

The 2022-23 IMPA contacts for Orchestra are:
VP: Michaela Tsai (orchestra@interlakemusic.org)
