I am not familiar with Faber, but I think that most method books are absolutely horrible in the early stages of learning and fully capable of slaughtering good music 😄
The only exception, afaik, are the John Thompson primer and the grade books. Before I went with Alfred, I went through JT grade one and I absolutely adored every single piece. The only reason why I went with Alfred was because for self study, JT moves very fast indeed plus there are no explanations. It assumes that a teacher will guide the student through the book.
I'm just about done with Alfred book 2. One more to go through and then I might continue where I left off with Thompson, just because I enjoyed those books so much.
Whoops, cross posted with you @BicBic! Congratulations on getting another public performance in, it must have been fun. Children can be a great audience. At any level 😁
