Exercise Categories:

- Perfect/Relative Pitch

The details:
Harmonomics has over 50 exercises (more coming in updates) that can each be heavily customized to fit the your individual needs, regardless of your level or the genre of music you are working on. Musicians interested in improving their recognition of chord types will be thrilled to explore Harmonomics' large library of chords (over 35 types), all of which can be played in different inversions. No other app offers such a wide variety of chords that can be played in so many different ways.

Statistics play a big role in Harmonomics. Each exercise keeps track of your accuracy, the number of questions answered, average time per question, and more, letting you review your progress and see when and how quickly you're improving. Harmonomics also awards "achievements" as you work, such as recognition of doing 1000 questions a month or 250 questions in a session, keeping you motivated to stay vigilant about your ear training work. If you're a student, you can choose to send reports of your stats to a teacher.

Most ear training apps offer a limited number of exercises, including simple interval identification, melodic dictation, and chord identification. Harmonomics has all of those as well as clever and practical variations, such as exercises that ask you which degree of a chord a certain note is or which inversion a chord is being played in. Plus, each exercise can be customized; for example, a chord identification exercise can be limited to just inverted dominant chords with alterations and made to play three chords in a row, all of which must be identified correctly. No other app offers that level of advanced exercise to meet the needs of professionals.

Absolutely brilliant

I’ve only been working with this for a day and can already report that, while there are some other helpful ear-training apps...and I have tried many this is hands-down the best one! The thoughtfulness, planning, organization, and intuitiveness that went into this is hugely impressive. It’s a serious app- not a toy. It literally can be used to train and help the very beginner to the experienced professional. Bravo!

The fact that the exercises are open -ended is great... meaning you simply end a session when you want rather than having the app choose a predetermined number of questions. You will need no other ear training apps. Just get this one if you are lucky enough to stumble on it.

My only complaint.. which isn’t really a complaint against the app itself is that for me it didn’t come up high enough when I did a simple search for “ear training” apps.. then I found it briefly and then accidentally closed out then searched through dozens of (far weaker) ear-training apps.. hoping it would appear on the “you may also like” lists. Thankfully I found it again after 20-39 min but this should be the first option to appear! Get it !!

The best ear training app available

This is the best ear training app I've found on the App Store. I started ear training about 6 months ago and I've purchased about 7 ear training apps. I've searched the App Store several times and for some reason I had never seen this one before. This one is the most comprehensive and includes many features I had been looking for, but haven't found in other apps.

The hands free mode is a must for me. For my work I do a lot of driving. The other hands free apps I've found are very limited with the options and I started to hit some plateaus.

Honestly, for the price this app is a steal. You'd have to buy several apps to get all the features of this one, and you'd still be missing some functionality.

Relative pitch, perfect pitch, chords, progressions, scales, so good

This app is the best for ear training. It should be a required app for amateur and professional musicians. I was just wanting an one octave relative pitch app. This is so much more even with perfect pitch. I like the awards as well. I’ve gotten 60% to 90% on one’s I’ve tried. I’ve just begun and didn’t think I had a very good ear. I love this app so much, thank you for making it. This app is a steal at this price.
