## Theory Lessons Reviews in Vereinigte Staaten

### ***-- "IPad issue"
None of the directional arrows work, nor any other guidance symbols. Also, text panels are cut off at the bottom and cannot be resized. The course does not begin at the beginning, and I can’t go back to see what I missed, though having some theory already, it’s mostly review at this point. But if you’re going to charge ANYTHING, make sure what you’re charging for actually works.
-- PJ-S, 2024-12-29

### ****- "Review of musictheory.net"
Musictheory.net is an excellent free resource for teachers and students. Being technologically challenged, I like the simplicity of it. The site accomplishes its purpose without frills. Though it might not be as exciting as an online game, it seems to challenge students appropriately. It can be used to teach a new concept or review old concepts, as an assessment tool, and for students to practice. Student can easily go online and practice, put their knowledge to the test, or complete an assignment. I am eager to use the Interval Identification exercise for students to practice and track their own progress.
-- ioanna tsaka, 2024-06-08

### ***-- "Good but missing features"
There is a practice mode that is on the website version. It seems like the app is a lackluster version of the website. For a more expensive alternative, I would expect either the practice exercises or other practice features to be implemented. 

A great offline version for the lessons but not much else. The website offers the same, comprehensive lessons as well as activities/ games to help solidify and check in on your learning for free. 

It has the most user friendly diagrams and lessons that I’ve seen compared to other apps.
-- oooooooooofffffooooooooooo, 2024-01-31

### ***-- "A lot left to be desired"
This app would work as referenced to those who are thoroughly trained in music theory NOTFOR LEARNING IT
-- pookie050, 2022-11-25

### ***** "Awesome app"
Would highly recommend
-- vikki-panthersfan, 2022-11-13

### ****- "Very good BUT"
This honestly is I would say the best music theory app out there I do with that between this app “Theory” and “Tenuto” that is would be more helpful in memorizing things like maybe implementing something for practice.

Also I kinda wish “Theory” had a thing in the scales section to learn about pentatonic scales and blues scales. Also to learn to apply concert pitch to different instruments. 

Thanks I hope you guys are improving things also honestly this app is extremely good you should honestly have people pay for it so you can have the time to update it and stuff and implement those things.
-- Bryce Novy, 2021-11-20

### ***-- "needs practice modes from the website"
needs practice modes from the website
-- Music theory . net user, 2021-08-04

### ***** "Truly Very Nice"
I had needed a great music theory app, and this fulfills my need quite perfectly.

The teaching is laid out in a very easy-to-understand format with attractive interactive user-friendly diagrams.

By the end of the first lesson, I felt as if I’d learnt quite a lot. And all without any effort at all. It’s unbelievable!

I already have an excellent practical practice app, in form of playgroundsessions app, that I had bought in a package deal along with a baby grand piano. 

But I had found the hands-on playgroundsessions teaching tool to be slightly lacking in deep music theory support.

So I went looking for something to compliment the playgroundsessions hands-on app, and to hence fully round out my musical education. 

Now I have one app for hands-on practice, and this one, for in-depth theory learning.

This is great!

### *---- "Not worth $1"
This is so lame for a $4 app.  Don’t buy. I would like a refund.
-- Grizzzzzzzzzzzzzz, 2021-01-13

### *---- "You have to be kidding me"
Its a list of bullet points with a couple of gifs. The positive reviews here must be a scam. Worthless.
-- cancelHoo, 2021-01-06

### ***** "Can’t open app."
The app is working again, all I needed was to delete it and put it back in my phone. Works perfectly.
-- Flyboy5527, 2020-12-01

### ***** "Thank you!"
I appreciate the time you folks spent making this app! I would understand if you charged for it, but I am so thankful that I was able to use it for free. 
Thank you for helping spread this knowledge and make it accessible :)
-- jakrybear, 2020-10-29

### ***** "This app is a jewel"
I love this app. It is simple in its format but highly effective in conveying this not-so-easy-to-grasp material. It is better than all the music theory books I have read to date! What a nice contribution.
-- Nain Jaune, 2020-08-01

### *---- "Doesn’t have the practice section"
I bought this app expecting to get all the features that they offer on their website, like the practice section. However, after buying the app, I found out that this is just the theory section and doesn’t have any of the other tools. It’s a whole different app for that. I wish I could get a refund on this app. 
I’ll still buy the tool app since that’s an amazing feature they have on their website.
-- Peoxgx, 2020-03-03

### ***** "Pretty Good App!"
This app came in handy a lot in my Music Theory class and was well worth the money for me.
-- TimTissle, 2020-01-10

### ***** "App is Great!"
It’s a wonderful app honestly and truly and helpful as a refresher tool for my Praxis 2 exam coming up. The only problem is I was looking for some examples rather than explanations like they have on the website.
-- Smoothie15, 2019-06-17

### ****- "Simple and good. No scales though."
App is very simple and does the job. Adding scales would be appreciated.
-- alexander.kazakov, 2019-04-23

### ***** "Great learning tool."
This is a great way to learn the fundamentals of music theory.  I use its companion app Tenuto to practice what I learn.  Very highly recommended.
-- SnookFan, 2019-03-13

### ***-- "Please add more audio !!"
Great app but please add more audio examples. For instance, I am trying to learn more about compound meters or odd meters and there are NO audio examples !! Frankly I am a little annoyed coz that’s why I bought it. Otherwise it’s a nice app.
-- Ed15, 2019-01-24

### ***** "Elegant piece of work"
Great job. Covers the basics. A wonderful refresher and learned some new material as well. Having dabbled at coding, what a beautiful, refined piece of work. A keeper reference tool.
-- bldrtom, 2019-01-16
