Finally got my kid to work on ear training!
We have been doing it for a total of about 30 minutes over 2 weeks, and every night I play just a few notes on the piano to ask him to sing them, and he's started being able to accurately sing back "do" (middle C) most of the time when I play and sing it. This is a big deal for a kid who resisted learning this to suddenly be asking me "can you play re and mi next?" And I think it's because this app gives the notes personalities.
I have perfect pitch. We have a piano, two guitars, a harmonica, drums at home, we have done the group style music classes. Believe me when I say I am committed to helping my kid learn pitch. But my child has shown absolutely no interest in music lessons. This is the FIRST TIME he has started to repeat "do, re," etc. after me!
I think this app is perfect for a child between 4-6 (maybe younger or older) when you want them to start ear training or being interested in musical notation, and who isn't yet interested in doing this on a musical instrument. You need to help them use the app at first - it would be better if the instructions were made for a believe, but as is, the adult has to kind of learn and explore the app at the same time as a child does for the first few sessions. After that, I can hand the phone to my child to play but I still need to be around to correct and to encourage him to sing the notes.
I do wish there were 6x as many lessons at the most basic level. The incentives worked to try to unlock the guitar and other musical instruments, but it gets difficult too quickly.
For the person who has sound issues: you have to flip your phone ringer on the side of the phone on for this to work.
