What AMEB level is Canon in D and Mozart Sonata in C Major?
Moonlight, Sonata & Rondo are about the same. Sonata in C (if it’s what I’m thinking of) is slightly easier. Remember that Moonlight has 3 sections & though it’s probably as easy as Sonata, the 3rd movement is vicious. So if you want an easier one, go with Sonata. As for the Canon, there is no official version of it since it’s originally a violin piece but people have transposed it for the piano. There is a version for your gr. 5 level (Since you mention Sonatina in C by Kuhlau I imagine it’s the same level). Yet there is also a higher level, but probably still lower than Sonata in C.
