This app is the first of its kind to measure the interval by moving around two notes on the staff.

* Interval Measuring: Interval measuring is straightforward in this app. If you change the height of the note the interval is automatically measured. You can also study in a more systematic way because the number of semitones appears along with the name of the interval.

* Interval Test: Once you become more familiar with music intervals try solving some interval questions. The random probability allows for a wide range of interval questions to be set. Interval questions are shown on the score and the keyboard. Even if you are not familiar with intervals you can answer the questions easily by counting the semitones of the two notes.

* Interval Ear Training: Interval Ear Training generally involves listening to the sound of an interval and writing it on the score. We have created app functions which allow you to notate intervals using this method.
Press the play button and listen to the sound of the interval. Next change the note and notate it. You can check the answer either in text format or on a score. If you select the text option you will only be shown whether the answer is correct or not so you can practice interval ear training until you get the right answer.

* Interval Sight Singing: If you press the play button you can hear the sound of the interval. If you use this option you can practice interval sight singing.
