## What is EarProg?

The skill of identifying the musical notes of a melody is one of the most important skills for any musician. But being able to identify chord progressions is the closest thing to having superpowers. Knowing how to identify chord progressions opens the door to a world of possibilities as a musician, which will allow you to improve your songwriting, improvisations, jams onstage...

EarProg is the ultimate ear training app to help you identify chord progressions. With this app, you can train your ear to learn how to identify 60 different chord progressions.

Press “Play" button. When you press that button, it will sound a random progression. Tap the progressions below. If your answer is wrong you should press the "Replay" button to listen again to the progression and try again your answer.

EarProg features all these chord progressions separated into three categories:

-Standard: The most commonly used chord progressions in pop-rock music over the past 75 years. Basic movements of 2 and 3 chords that are the foundation of more complex structures. The audio examples are based on the key of C major;

I - C major
II - D minor
III - E minor
IV - F major
V - G major
VI - A minor

-Four Chords: A careful selection of progressions with 4 chords. Very common in choruses, intros...

Again, all examples are in the key of C major;

I - C major
II - D minor
III - E minor
IV - F major
V - G major
VI - A minor

-Minor. There are a large number of songs arranged in a minor key. If in addition to mastering chord progressions in a major key, you can identify progressions in a minor key, you will become an extremely exceptional musician. No situation will have any difficulty for you. 

In this section, the examples are based on the key of A minor;

I - A minor
II - B dim
III - C major
IV - D minor
V - E minor
VI - F major
VII - G major

So you can listen to the chord progressions available in the app, you have a screen where all the progressions are grouped together.

Forget the scoring pressure. Ear training is not a competition. That's why no scoring is used in this app. Simply open the app and practice at your own pace, without pressure, for as long as you want. Mastering ear training is a gradual work. We're musicians, not Superbowl players!!

Become a first-class musician with EarProg.

### 5/5 — Thank you

*2022-11-19*

Thank you for producing this app.  I would also be interested in purchasing a version that takes these progressions further.  
1). adding 7ths, 9ths, etc.  
2) adding secondary dominants 
3). Adding modulations to closely related keys (relative major/minor)
4). Adding borrowed chords from modes

Thanks again

### 5/5 — Great Ear Training Tool

*2021-12-10*

For beginners starting out or advanced students brushing up on their theory and ear training.

### 5/5 — Love the App

*2021-10-27, version 1.1*

Hey guys great app for straight forward, I know what’s going on and just need to isolate and train my progression ear.

One thing in the minor section,  the I - IV - V - IV answer is actually to a I - V - IV - V question. If we could rectify this that would be awesome.

### 1/5 — Only 1 key and 1 voicing for each chord

*2019-11-25*

Only 1 key and 1 voicing for each chord

### 3/5 — Roman numerals should correspond to Major & minor chords

*2019-09-23, version 1.1*

I think the App is helpful, but it’s really not good for the users to see a major scale chord progression such as I-III-IV-V or I-II-V-VI in all caps when they should read I-iii-IV-V or I-ii-V-vi. If the App is going to be efficient at ear training, it is imperative that the student be able to hear and see the difference between major and minor chords. The App should follow standard music notation for chords written in Roman numerals.

### 1/5 — No sound

*2019-09-12*

Rebooted phone, etc. Please help or refund ASAP

### 4/5 — One niggle..

*2019-07-13*

Can you please fix the problem in “minor“, where it says the answer is I-IV-V-IV and the right answer is I-V-IV-V thank you

I am now getting on quite well with this app and I'm finding it very useful, particularly the minor progressions on which I appear to be very weak!
I still don't understand the colour coding or the order in which the answers are displayed? Also, I think the answers would be clearer if minor chords are notated in lowercase Roman numerals?
Just a thought… Thanks very much for the app.

### 4/5 — Ignore my 1 star review...

*2018-11-27*

If the phone is in vibration mode, no sound played. When I switched it to ringer mode, it worked fine.

### 1/5 — ! No sound

*2018-05-08*

Be careful! The app no sound!

**Developer response:** Sorry about that. The app has been fully tested. Can you tell me which iPhone model you have?

### 1/5 — What happened to sound?

*2018-04-01*

Since I updated to 11.3, no sound on any mode.

**Developer response:** Sorry about that. The app runs perfect on 11.3. Can you tell me which iPhone model you have?
