The Sylphonies

The Sylphonies are the Glee club of Crystal Cove High in Toledo, Ohio. They are first mentioned in Bubblegum Pink as one of the choirs competing against Rising Phoenix at the 2030 Western Ohio Sectional Championship, and their only appearance is during the competition itself, in Telling the World, in which they perform This is How We Do by Katy Perry. They are described as "a little too clean-cut", and Rachel seems to think of them as being like Aural Intensity minus the pandering.
