Sharon Bill has now uploaded a full course of study for ABRSM Music Theory Grades 1, 2 and 3 onto YouTube. There are playlists for each ABRSM grade so you can start at page one of each of the relevant ABRSM Music Theory Workbook and study in realtime with Sharon through the entire book.
I can vouch for the teaching as when we homeschooled our children I did ABRSM Grades 1, 2 and 3 and I achieved 100% in grades 1 and 2 and a distinction in grade 3 when I took the music theory examination. Below is the introduction video to the ABRSM Grade 1 YouTube playlist. The introduction covers Sharon’s outline to her course of Study right through to Grade 5.
For each of the series there is a FREE DOWNLOAD PDF guide from Sharon’s website in A4 and US Letter sizes that she refers to in each of the videos. Sharon has used these for over 25 years with all of her private music tuition pupils.
