Music theory can be empowering, exciting, and one of the biggest tools in your creative arsenal. Whether you already play an instrument or are just learning, Waay teaches you how to stitch notes together into melodies, chords, and even songs. Read what experts and users are saying about Waay:

"The app is very smooth, and a great resource for learning more about music theory. I found the scale exercises to be very helpful, and I suspect I'll go back to them as a way of keeping those skills sharp."
– Sean Garland (App reviewer at iOS MARS)

“This is a really helpful app. I have been an amateur musician for many years and your circle of fifths explanation is the best I've ever heard. Thanks for putting this app together and sharing it with the world!”
– Tony Smith (Amateur musician)

"If you want a solid introduction to the kind of practical music theory that will get you writing songs that make harmonic sense, then Waay looks like a good place to start."
– John Walden (App reviewer at Music App Blog)

"If only the theory class I dropped out of was as easy and engaging! This is definitely the best way to learn theory. Waay to go!"
– Rob Davis (Guitarist)

“Whether you are a beginner or someone who wants to brush up on their music theory skills, I would recommend Waay!”
– Lisa Chan (Pianist, singer, and music instructor)


You're writing a new song, but keep getting stuck. What chords sound good together? What melody fits those chords? Waay helps you master these skills with its interactive exercises, video lessons, and progress tracking tools.

Waay teaches applied music theory—stuff you can take straight to your instrument and use. Want to know what notes sound good together? Waay covers that in the first course called "Melodies." Want to know which chords fit well together, and how to build any major, minor, or diminished chord? That's what the second course, "Chords," is all about.

Using a combination of bite-size video lessons and interactive exercises, Waay takes you from the basics of notes, steps, and keys all the way through chords, chord progressions, and more. The first course even comes completely free with the app, including 8 video lessons and 9 interactive exercises. Here's what else you get with Waay:

• Music theory tailored for beginners and aspiring songwriters
• Video lessons with many musical examples

The key that finally opened the door

I struggled for YEARS with music theory, everyone kept raving about how simple it is, and I always felt confused and stubborn with anything regarding music theory. However I owe everything to this app for finally unlocking the door, it explained everything easily and effortlessly and now I’m able to learn even more theory after using this as my building block. If you still don’t understand or get frustrated do not give up! I even deleted this app from my phone for a year, came back and now I’m finally understanding of music theory. Thank you to the creators of this app!

I have been through multiple musical theory apps but could never really grasp anything. With this app, I do not exaggerate, I learned how to build major and minor scales, the circle of fifths, the circle of fourths, the perfect 5th in chords, the diminutive 5th.... and on and on in ONE DAY. Not only did I learn them, I understand them!! I’ve played guitar for years but have been unable to write my own music because I lacked the knowledge this app gave me in one day. I’ve wasted weeks on other apps, books, and even musical coaches. This app is amazing!!!!!

Great App!

This app is great for learning music theory in a fun way. It teaches you the theory in a a simple and easy to understand way too. This may not be fair but I want to give a four star to encourage the app developers to add a feature that I thing would complete the app; That is to have the notes on a virtual piano. Because why forgo the opportunity to both learn theory and solidify our knowledge of where all the notes lie on the piano?
Great job developer guys and gals?

Developer Response ,

Hi Ali, glad to hear you're enjoying Waay! Thanks for the feedback. That's an interesting idea to enter exercise answers on a virtual piano, though right now the app is geared towards *any* instrument and I think it's important to reach people "where they live." For example, if a guitar player is learning music theory with Waay, I want them to feel equally at home. :)

That said, there could be an interesting way to approach this which ticks off all boxes, so I've made a note of your feedback for future versions. Please don't hesitate to get in touch with any future questions/comments at alex[at]tenkettles[dot]com. -Alex

P.S. We offer a free virtual instrument on our website too, if you're interested in using it alongside Waay (or anything else). You can find it at
