For many years I would not use the method of rhymes, however since that firm decision was made I have learnt much more about learning styles and inclusivity. It cannot be denied that for some learners this method helps a lot more than flashcards and 'just remember'.
It also has to be remembered that I learnt using this method and it worked for me. What I would say is this is not the only way to achieve the understanding of the note names. You can use it alongside other methods, often a multi-method attach is the best way forward.
If you require any additional tutorial help please see the other videos in this series or ask in the comments.
