Theory Lessons Reviews


Great way to start!  StalinMcPutin  5 star

This app is a great kickstart into music theory! I've used this for a couple weeks and I've already have improved in my musicianship and overall understanding. Thanks for this great app!!


Tired Of Confusing Theory Books? Buy this.  :Amy:  5 star

Clear and precise music theory explanations. Music Theory has always confused me, but this app's visual design/animation is very helpful along with the material presented. Buy this $3 dollar app! No need to pay for tons of theory books.


Just info no interaction  Famwith3  1 star

This app is just information. I am looking for something for my tweets to practice theory. This is not it.

Well translated !  Mad Thrasher  5 star

Very well translated. couldn't be more clarified!


Wow Just "WOW"  Fluffyduffydo  5 star

Never knew how easy it was to learn until I got this app. Everything is put plain as day in front of you and everything is there for you if you need to return and relearn anything. Easy and quick!!! Love this app! Music made easy!


Woah  Jzo18  5 star

Gonna be honest this app, in addition to the website, taught me all the music theory I know and it was made so simple and easy. Thank you for making it easy for beginner musicians to learn this. I hope you guys add more stuff soon though.


Excellent  bentford  5 star

Love this app. A cheap way to learn the fundamentals of music theory.


Amended - Audio doesn't work  TheOnePutter  4 star

Audio DOES work. Only available on some slides. Developer can stop negative reviews by making it more clear that audio isn't available on all slides. (Old Review: Installed on 6+. Audio grayed out. What's the point if there's no audio?)


Outstanding job! One tweak.  Hi9087654321  5 star

I am truly amazed by the quality of this app. Well worth the money. I have learned so much here and I feel as though I can really take music to the next level. I have one suggestion, however. It is tough to retain all of this knowledge without having a good way to practice some of these lessons. I understand that there is a sister app, Tenuto? I would be one hundred percent more satisfied if you released an update for this app or Tenuto that included exercises identifying chord progressions, practicing things like the more complicated triads and such; the vocabulary is very hard to retain despite how well the lessons were put together. Thank you for your hard work!


Audio Doesn't Work  theflyingnun  2 star

I just downloaded this app onto my iPad Air 2, but audio controls are greyed out and unavailable.

Great way to quickly learn music theory  Hyyyyppppeeerrrrr  5 star

I really like the layout and design of the lessons, with animated illustrations on the staff so that you can see what you're learning.


Very  mica15  5 star

Useful application. As a total beginner this application has a lot to teach +It has lots of lessons, I've only made it through three or five out of about 39. -It doesn't have a position save or favourites. +Uses sound and moving diagrams to explain. +Concise wording. +Organized by category of music theory, e.g. "Basics," "Rhythm and Meter," etc.


Excellent App  Yoshiracer09  5 star

By far the easiest and best app for anyone to learn music theory. I love it!


Music Theory App  Truheo321  5 star

It's simply the best 1.99 spent to improve musical knowledge.


Best application for serious music theory learner  Jeeesi  5 star

I start to learn piano and need to learn music theory as well, after some while I found I really love those music knowledge and want to study seriously , so I got some textbook for music college, but feel a little frustrated since I am self-taught. This application did me a HUGE favor to understand the basic rule. It worth every SINGLE PENNY! Thanks to the great musician who create it!


Awesome.  Cdcdude  5 star

Great for brushing up on some theory while just hanging around. Highly recommended.

Straightforward  Jolly Roger 1  5 star

The lessons are straightforward and packed with great information...without the fluff. Great for learning and as a reference.


Great app  Kdapple..'  5 star

Definatly one of the better ones!


Excellent  Renn71  5 star

As a music instructor, I usually take students who have some background in theory or expertise at their instrument. Branching out to a new student who wants to learn how to read standard notation, I wondered how to easily and systematic start from the basics. After reviewing the material on, I am working in conjunction with this app because it is so fantastic and easy for my students to understand. I will be downloading the Tenuto app as well soon to have the exercises available. Great product! Thank you so much for being so concise and easy to follow. The perfect way to learn basic music theory! -Jonathan A.


Good App!  Hhghjngcdghkkngdf  5 star
