Extremely helpful and also very organised. It's clear, where to find which information and you can also practise your hearing with intervals, chords, etc. I never really had much to do with music theory, but this was all easily understandable and I'm getting into it now 😊 Only negative thing is that you have to pay to unlock some features, it's understandable, but still sad :/

i think it's really good for learning music theory. cuz I, a novice, know as good as nothing about music theory, and still this app is a big help on the first day! even the free version. i haven't even seen all the features—since I'm just starting on the app—but I'd recommend it to a lot of people. Ooh, and also, on top of it being good to use, I find it really fun :)

The piano worked half of the time. I thought the app would be like flashcards to work through all the scales, but it basically just provided definitions and one example. It's ok, but doesn't meet what I'm looking for.
