ABRSMGrade 8 is the highest grade, and it probably compares with your grade 10.Grade 8 ABRSM does not even begin to include the easier virtuoso repertory. All but two of the Chopin etudes are considered well beyond grade 8. Best wishes,Bernhard.Grade 8 is not the highest in ABRSM examination system.After Grade 8 there is Diploma, LRSM (Licentiship) and FRSM (Fellowship)Diploma is something like easy Beethoven sonata (Pathetique or Moonlight)LRSM is stuff like Chopin etudes and Liszt etudes (as stated in the syllabus) and hard beethoven sonataFRSM is something like LIszt sonata, Ravel Gaspard, Chopin sonata....It's easy to find the syllabus of the ABRSM exam syllabus on their website.My friend just took the FRSM with ALL Liszt programme.
This question is kind of unanswerable, as pieces can only get so easy (whereas pieces get infinitely hard).I don't know exactly the skill level of your student, but Traumerie is a good piece to experiment vocalisation with- also his Album for the Young.Mozart is a pretty consistent composer of some fairly playable pieces.
Bernard ,Thank you so much for this most wonderful thread. As a newish player this thread has provided much relief from insipid method books. I suspect my teacher will roll his eyes if I ever say again, "well I was on piano street...." m1469 - and thanks for reviving this on occasion, your dedication is an inspiration.Dorie
