iHarmony is a fully complete collection of all the scales, chords and harmonizations you can find in music. It's very common for musicians getting confused about music theory...

"what notes the G# diminished 7 chord is made of?"
"what are the degrees of the Bebop Dominant scale?"

or even worse...

"what's the harmonization for D# Melodic Minor scale?"

No more getting annoyed to search the web about that Lydian 7b scale, the Neapolitan scale, or the Whole tone scale!

iHarmony offers you the most complete set of scales, chords, and harmonizations with over than 1500 entries and audio clips! The whole musical harmony always with you on your iPhone, iPod Touch or iPad.

You can choose between English (C, D, E…), Italian (Do, Re, Mi…), German (C, D, ...H), and French (Ut, Re, Mi...) notations.
Extremely useful when you write music, before a jam with your band, to do the functional analysis of jazz standards or just to do your musical homework.

Particular attention to accessibility and VoiceOver support.

iOS 13 dark mode support.

A must for every kind of musician!

Very useful

There are many apps available that show chord and scale diagrams, so why is this app IMHO so great? Well, many of us own a big fat chord book and probalbly a scale book or three - but how many of those chords etc are we able to actually remember. When you learn the formulas to build a scale or harmonies you are opening up a lot of possibilities - instead of trying to memorize chords you can begin to build them in any position. This app is another useful tool for a musians toolbox, that complements and enhances other approaches (such as chord books etc) It also makes an indispensable reference resource.

This is one of the best apps I have. It has helped me pass my Grade 5 Jazz. I use it often to remind me how some of those tricky chords are made up, and you can hear it too. Life saver.

Not really. Does what it says, but could do so much better with the piano keys indicated, instead of a plain text that it makes use of. Also, zooming would help it a lot, or a larger font, as some information is basically indecipherable due to the miniscule font size. On the other hand, can someone please tell me what does the delta sign that is being used here and there in this app means? Is is a substitute for an otherwise different notation symbol? It appears a bunch of times and got me quite confused, honestly... Well, anyway - I've spent my money now, so I'm looking forward to a decent update, that hopefully comes.
