Classes are organized by skill level; typically instructors will teach a tune, providing guidance on technique within the context of the tune. All classes are held on Saturday: one class in the morning and another in the afternoon. You will have a different instructor for each class.
Workshops are topic-based. All workshops take place on Sunday afternoon. You will choose your workshop when you register; see the Workshops page for details on this year's workshops.
The reedmaking workshop runs all weekend (Saturday morning, Saturday afternoon, Sunday morning, and Sunday afternoon), but it ends just in time for you to take one of the Sunday afternoon workshops.
