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
• Interactive exercises on keys, intervals, scales, and more
• Built-in tools to track your progress
• No connection required! Lesson videos will download automatically as soon as you're on WiFi, and then you'll never need a connection again to use the app. Perfect for your subway commutes and plane adventures.

Seventh Chords Are NOT included in CHORDS In-App Purchase


If you're an intermediate or advanced musician looking for an app to practice chords, scales, modes, etc. this app only covers the basics (CHORDS in-app purchase does not include Seventh Chords). Would be excellent if Seventh Chords and (practical) ascending melodic minor and harmonic minor scales were included. Hopefully, an additional course/update will be added in the near future. The app is a great start for beginners (covers basic intervals, triads, Major and natural minor scales.)

Developer Response

Thanks for the kind words about Waay, and for the feedback! The app is indeed geared toward beginners, but for future courses I definitely agree that seventh chords would be a great addition. And for readers of this review wondering whether the material is a good fit for them, check out the App Store description for the specific topics we cover. Thanks again, Alex

The Best!!!


This app is addictive!! I’ve been a long time couch strummer who’s blindly followed tabs. This has been my favorite app since my purchase. Knowing what I know now, I would gladly pay 10 times what I paid. My mind is growing musically with a new aha moment each day. Thank youSo much; this app rocks!



This app is rad. I’ve been using it for about an hour and I’m trippin out at how fast I’m understanding theory. Way to break it down in an extremely easy to understand way. 👍🏼
