Here are some of the ways teachers around the world are using Theta Music Trainer:

- Introduce new concepts through games
One of the great things about games is that they provide immediate feedback in real time. Students are often quicker to grasp new music theory concepts when they are presented in a game format.

- Use games in place of drills
Rather than giving your students tedious drills, you can use games to reinforce key concepts taught in class. The necessary repetition becomes much more palatable to students in a game environment.

- Assign games for homework
Not only will your students love this, but you can get true assessments of each student's ability in a wide range of areas including scales, rhythms, chords, tuning and more - without spending a huge amount of time grading.

- Hold classroom competitions
Choose a game for your desired area for practice and see who can complete the most levels. Students can compete individually or in teams. You can even have classrooms compete against one another.

Teaching aural skills and music theory can be tough. Many students have a hard time grasping the basic concepts and struggle with the repetition needed for mastery. Games inject an element of variety and fun into the development of basic music skills. Students become inspired, motivated and engaged in music learning. Have fun and save time as your students develop core music skills in an engaging and effective way.

Crashes, please fix it soon!!

One tool within the app, Dango Brothers, will run a few times then it crashes. I’m running it on an iPad Air. This and several of the other included tools are excellent and definitely worth using. It is annoying that it crashes and has to be restarted constantly. I have reservations about recommending the app in it’s present condition, and really wish the developers would fix it.

Love it!

Okay, so I'm a music major in college and a class I'm taking right now is Music Theory I. Well I had a little theory before I came to college so I'm doing decently so far. But most of our fairly large class is having a really hard time. Well, our professor did some research and digging and found this app. He made all of us download it and do assignments on it. Well I personally love it! It's so addicting and it really is helpful. All of my classmates love it and are learning much quicker. And it's a fun competition to see who can get the highest belt. My only problem is that there are a few bugs but nothing major. Like sometimes I can't open my assignments. I also don't personally care for how the circle of fifths is set it up. Half of it is off set and it bugs me. Other that this app is great and I highly recommend!

Great App!

If you’re a music teacher, be it private or public, you can also setup a ‘class’ on their website that your students can log into so you can observe their progress outside of lessons. :) The visuals should help with keeping the attention of younger students well, too! It won’t teach the fundamentals of part-writing, no- but nonetheless there is a LOT of material that this app/website covers, with difficulty levels that start with the first-timer and over the course of 30 levels gradually move all the way up through advanced and on to professional (if not then some)!
