Is Prelude in C major hard?
Yup, it's not hard to play the notes but it's hard to play it legato and evenly. I love Jarrett's version. Phrasing and dynamic directions can be tricky because of the continuous patterns of notes. The prelude and its accompanied fugue is actually one of the AMEB (australian music exam board) grade 8 exam pieces.
What level is Prelude in C Major?
THe Edexcel difficulty guide classifies it as a Grade 5, musicallyminded. So it should definitely be classified as a 'harder' piece for GCSE. It would be a 'standard' piece for AS level.
