During NZ’s first lockdown I began compiling a list of the pieces that have been part of the ABRSM piano examination syllabus for Grades 1 - 5. This list has been updated in March 2024.
The List category has changed its designation over the years. There is another post on this website covering a little of the history of the ABRSM’s piano exams.
The following is a list of all of the Grade 3 20C pieces that I have collated.
