This is an application that can help you to develop your ear for music.

The way to use it is very easy. You just need to do the same thing that you do with a normal ear for music, that is, listen to a song and try to sing the melody.

This application has four different songs, and for each one of them, you can choose one of the four melodies that are available.

It is also possible to add your own music, or even your own melody, and try to sing it.

The results are saved, and they are available to view at any time.
