Beethoven's Moonlight Sonata is No.14 in C-sharp minor and is one of his most famous Piano Sonatas, particularly the first movement which we present here. This movement is sometimes labelled "Quasi una fantasia" (like a Fantasy) though it doesn't suggest moonlight in any way. Rather it is quite a dark quiet movement with an insistent triplet rhythm, and the challenge for the pianist is to keep this even with just the right nuances of crescendo and rubato in appropriate places. We have included some suggested pedalling suitable for a modern piano, though the aim is to achieve a smooth sustained legato without muddying the harmonies.
