i played both of these before and this is all in my opinion: (plz tell me if im refering to the wrong piece)
Beethoven Op13 Pathetique Sonata
Actually depends on what movement are u going to play, which i presume if this is played in HSC, it wont be the whole sonata, so im going to do some sort of break down.
1st Movement - Grave, Allegro di molto e con brio
i would reckon this is a grade 6-7 piece (disregarding the length of piece), it is a pretty standard piece really coz in the allegro bit, there arnt much in it and it is not that difficult, personally i liked the second half of development (Bar137) and the Grave section(s)
2nd Movement - Adagio cantabile
A potential "make the marker go to sleep" piece if not performed correctly, but still i would reckon is about Grade 6
3rd Movement - Rondo
My fav in this movement, Grade 6 standard because of the simplicity of the structure, but with the right style of playing, this could be a very good piece.
Debussy - Suite bergamasque - Clair de lune
Grade 7-8 standard, a very expressionate piece, needs a lot of attention in playing the piece, learning it may be easy, but not playing it.
