The Really Useful Piano Reference Cards - 12 Pack (1 per Key Signature) - Learn & Master Piano Music Theory with Our Fully Illustrated Scales & Chord Cards - Perfect for Beginners & Music Producers

Excellent reference cards and all you need to get started. Just memorize the major shapes and figure it out from there: Major=1+3+5 (you memorize this shape), Minor=1+b3+5 (just lower the third), Augmented=1+3+#5 (just raise the fifth), Diminished=1+b3+b5 (lower the third and fifth), etc. Learning this way (with seventh and extended chords too) empowers you to play different chords on the spot. You will never memorize them all.I suggest you laminate them. You’ll need to cut the cards a little (A4 size), if you use letter size laminates for the cards to fit. It’s also a good idea to get a chord encyclopedia, since your never going to memorize them all. I recommend the one I got. Picture Chord Encyclopedia: Photos, Diagrams and Music Notation for Over 1,600 Keyboard Chords by Hal Leonard Corp. Pretty much nothing will get past you with these two tools in hand. 😎

These cards are a fabulous reference and learning tool. They give multiple scales and chord diagrams for each musical key. You don't have to spend so much time learning music theory. Identify the key you're using and follow the guide. I think these cards are so great that I had them laminated. I punched holes in them and I store them in a binder.

These cards are great. Very helpful and a valuable learning tool. Also bought for a set for a relative.

These cards have greatly augmented my ability to play in an organized fashion within a specific key. My playing now sounds much more naturally flowing and understandably coherent.Highly recommend.I am buying a second set for my daughter-in-law and grandchildrens’ use.

I like the Font size. Easy to see. Would be nice if they were laminated.

Really great and useful. Laminate if possible.

Love these cards. So easy to learn scales and chords. Brilliant idea!

Slightly bigger than a standard sheet of paper, so it kind of sticks out of the page protectors I put them in.If you really want to use it well put it in page protectors and into a binder, otherwise you'll be shuffling them around.
