As you have may have noticed, I have "affiliate link" noted on my site when I mention method books I use. As an independent musician and music teacher, I'm part of the Amazon Associates program, where I can earn a small amount of income - at no additional cost to you - if a purchase is made via a link from my site. It's not a huge amount, but every little bit helps me continue to deliver great music and music education - and for that, I thank you!
