  1. This is a really cool website!  I love music, but don’t play it because I don’t know how!  But, due to the content I’ve come across here now, I’m given an incentive to learn.  Not since junior high had I touched a musical instrument of any kind!

    I’m also hoping more parents come across this and encourage their kids to participate.  Listening to music is one plus, but being able to play it is so much better!  And, for children (of all ages), to learn how to play is such an experience!  It boosts confidence, not to mention acquire a talent most people wish they have but don’t.

    1. Thanks for sharing your thoughts, Millie. Great to hear you have become interested in music and we wish you a happy learning journey. 

  2. Hello, I believe that this article was made for me! I was looking for free music lessons for me and my nephew ans here you are! I really like the fact that music theory is available to everyone, especially during these times of lockdown where you can’t really enjoy life the way you used to. However, I am skeptical about Udemy because all the courses I’ve seen there were not free? Anyway, thanks for the useful information!

    1. Udemy also offers free courses like “Music Theory for Beginners”. Unlike paid courses, they don’t come with a completion certificate though. To enroll in a free course, you only need to create a basic Udemy account.
