This app was created with the objective of learning to distinguish each note from a scale, by hearing the first chord of the tonality and then the note. When clicking on the "Play" button, you can here the audio with the mentioned content. Then you can select the corresponding degree and its quality in relation to the scale. You can submit your answer by clicking "Submit". Some exercises (in level 2 and 3) require more than one answer, use the submit button as necessary. Watch the video for a demo.
There are just 3 levels available right now, more will be uploaded soon.
