Welcome I have only done Rock School, and just Grade 1 with two students (most of mine just learn for fun) but I highly recommend it – I even put myself through Grade 8 through RS and enjoyed the structure and what it covers! Both students passed and it was more in keeping with the style I teach!
Interesting, so it’s HELPING the singing teacher! Actually I’m going to go back on what I said – I actually only encourage Youtube for piano help rather than singing..
