Hi, I'm Eunyu.
I created these books to help you practice playing from chord symbols.
I hope you find joy in the music you play.
That's me playing in the video above. More videos on YouTube and Instagram.
Questions
I've never learned chords. Can I start with these books?
Yes. Set 1 introduces how chords are built. You'll need basic sheet-music reading skills to follow the daily practice pages.
Do I need to read sheet music fluently?
No. Basic sheet-music reading skills are enough to start the daily exercises. Being more comfortable reading music will help you learn faster. If reading sheet music is difficult, you can use our free theory book to practice chord progressions with keyboard shapes. It doesn't teach sheet-music reading.
Which set should I start with?
New to playing chords? Start with Set 1. Already comfortable with triads? You can start with Set 2. You can buy Set 2 later at its regular price. We don't currently offer an upgrade discount.
Is the bundle different from the two sets?
No. The bundle contains all 8 books from Set 1 and Set 2 and costs less than buying the sets separately. No books are duplicated between the sets.
Can I use the books on a tablet or print them?
Yes. You can read the PDFs on your own devices and print copies for personal study. Please don't share the files or printed copies.
How do I get the PDFs?
After purchase, we'll email you a download link. The link is valid for 30 days and allows up to 10 downloads per book. If it expires or you lose it, request a new link on our downloads page using the email address you used at checkout.
Can I get a refund?
Changed your mind? You can request a full refund within 14 days of purchase if you haven't started downloading any book in the set or bundle. Broken files are fixed or refunded. Refund policy →
