Rescheduling & Cancellation: Students must give 24 hours' notice to cancel or reschedule a lesson. If a student does not give 24 hours' notice the lesson will not be rescheduled and the student will be charged. If a student requests to reschedule a private lesson more than 24 hours in advance Vesper will make every effort to accommodate the request. One student-rescheduled lesson is allowed per student per month. Sorry, we are unable to refund missed group classes/camps. As working musicians, our teachers will occasionally have performances that conflict with lesson times. If this occurs, students will be notified in advance and will be provided with a substitute teacher for the lesson. Performances are necessary for our teachers to maintain their skills and value as educators.
