***** Highly addictive piano game. *****

A fun way to develop a better musical ear!

Great for experienced musicians and beginners.

Music students love this app.


Interval Ear Training can help improve:

• Interval recognition
• Sense of pitch
• Transcription skills
• Improvising skills
• Self esteem


How to Play:

• Tap "play" to hear the interval
• To hear the interval again, tap "replay"
• Use the piano to play the interval yourself
• Play often to improve your score!


MIDI In – Plug in your MIDI keyboard to enhance the experience! (Core MIDI compatible)

MIDI Out – If you have a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI, you can play Interval Ear Training using the sounds of that app.


Tips for the Beginners:

Use the + and - keyboard range control to set the keyboard to a small range such as "C, D" or "C, D, E".

Keep practicing, and as you progress you'll want to make the range larger.


Tips for the Pros:

Set "Feedback" to "Never" and turn on "Autoplay" to play continuously without ever missing a beat. Crank up the tempo to see how fast you can go!

For more advanced ear training features, you'll want to Unlock Pro Settings.


Interval Settings:

Tempo – 60 to 320 BPM

Keyboard Range – Starting at 2 notes in a major scale (ex. “C, D”) and up to 12 notes in a major scale (ex. “C, D, E, F, G, A, B, C, D, E, F, G”) with the ability to change octaves.

Feedback – Set to "Never" to stop all messages. Set to "Wrong" if you only want messages for incorrect intervals.

Sound – Set to "Piano" to hear the built-in piano sound. Set to "MIDI Out" to hear the sound of a music instrument app (such as a synth) that can run in "background mode" and accepts virtual Core MIDI.

Autoplay – Turn on to always play the next interval immediately. Turn off if you want to play the keyboard freely between intervals.

Key Labels – Turn off to remove note names on white keys.

Allow Unison – Turn off if you don't want the same note to be played twice in a row.


Pro Settings (requires in-app purchase):

Scale – 13 major scales

Difficulty - Diatonic, Random Tonic, Chromatic

Length – 2 to 6 notes


About the Difficulty Setting:

"Diatonic" uses notes from a major scale. This setting is recommended.

"Random Tonic" uses notes from a random major scale each time.

"Chromatic" mode is the "extreme mode" where any combination of notes is possible. As a result, strange intervals like the Augmented 2nd (ex. F to G#) are possible.


About the Score:

Interval Ear Training is all about self progression. Tap the score to reset at any time. The game goes on forever and the music never ends!

Amazing little app for amateur musicians

This app is great for becoming more familiar with intervals, which is one of the most valuable skills for anyone leaning music. It is fun to play and satisfying to master. I always choose this over some mobile game when I have nothing to do but a phone and access to sound, as it is just as enjoyable as a game if you are into music. Even if you just want to mess around with the keyboard, this app is perfect and enjoyable for any wannabe musician and I highly recommend it. My only complaint is that you cannot set it to play every interval from the same tonic, since it can be hard to get your eat to switch between keys so frequently.

Thanks so much for the review! You described my goal perfectly – to make this app as enjoyable as a game if you are into music. In a sense, it is a game... but it's certainly not a waste of time :) Your suggestion about having the interval start from the same tonic is interesting. I'll consider that for future development. Cheers!

Incredibly effective

I have (let's put it kindly) a shaky sense of pitch. I loaded this app on my phone earlier this week and have played roughly a thousand reps since then. I went from a little over 50% accuracy at the outset to a cumulative score of app. 65% during that time (I'm not sure if you can rest the counter to score individual sessions).

This morning, I loaded the app on my iPad and played 100 reps for a score of 87%. I don't know how happy that would make you, but this was a complete home run for me. If I can make this improvement, anyone can.

As highly recommended as any app I've used.

Thanks so much for the review! I agree, you've hit a home run! For the score, you can tap it to reset at any time. 87% is actually extremely good :) Sounds like you're ready to make the keyboard range larger using the + and - keyboard range control. Personally I consider 65% to be very good also. If your score is below that, it just means that you've found a challenging setting that is helping you to improve your ear training skills. Cheers!

Really nice

I tried a few other apps and frankly i found something special in each one. I like this one because its simple, effective,sounds good. I like the visual of the keyboard. Theres not really too much to say because it is so straight forward and simple. I just want to say thank you to the developers for taking the time to create a nice app thats easy to use. By the way the images are a good size so easy to read. I think anyone that tries this will benefit from it. Like i said i have tried others and still use them but this seems like my "go to" app. Enjoy

Developer Response ,

Wonderful! I'm glad you appreciate the simplicity and sound quality of the app. Thanks for taking the time to write a review :)
