Music Theory Intervals for iPhone
Download on the App Store

Identify simple and compound (greater than an octave) intervals by sight and sound. Hear the intervals played harmonically, melodically up, or melodically down.

Included intervals are major, minor, diminished, augmented 2nds, 3rds, 6ths, 7ths, and diminished, perfect, and augmented 4ths, 5ths, and octaves. You can exclude diminished and augmented 2nds, 3rds, 6ths, and 7ths.

There are a couple ways to determine the root notes of the intervals in the quiz. First, you can have the app generate random root notes. And Second, in between each question, you can set what the root will be for the following interval. In both situations, the interval will always be within the written range you've set in the preferences. So if you pick a root that would put the interval outside the range, the app will move the root so it fits.

Keep the intervals on the chosen staff by limiting how many ledger lines you want allowed. You can set this from 0 to 9.

Sight Reading or Ear Training

Turn off the sound to identify the intervals by notation alone, or cover the notation to test your ear. Descending melodic intervals is a good challenge if you feel up to it. If you've included all diminished and augmented intervals, you'll have to peak at the notation to be able to get the theoretically correct answers.

Four clef options (Treble, Alto, Tenor, and Bass)

Set the number of chances (1 to 3) to get the correct answer.

Number of questions can range from 1 to 100, and also set the quiz to grade only those questions answered. This allows you to test for a period of time, and finish at that point, regardless of the number answered. For example, see how many you can get right in 5 minutes.

There's a timer that records how much time was spent on the quiz. If you want, it can be turned off.

Choose how you want the quiz to look, ink on paper or chalk on a chalkboard.


Quickly see, filter by name, and edit this list of all saved scores.

You are able to delete selected scores, or all the scores at once.

Teachers may want to limit the access to the grades list, so it can be easily locked and unlocked within the app by using a password that is set in the iPad's Settings app. Just type the password as the student's name and the grades tab unlocks.

The recorded grades include the student's name, date and time the quiz was taken, all relevant quiz settings (clef, number of questions, etc.), and score (percentage and letter grade).

You can enter a name either in the module itself, or in the setup preferences. Just tap on the name and enter the new name.

Example of uses:

Use the timer to set an amount of time to work on a specific skill. Have a student work for 3 minutes and see how well they do. Set the quiz Preferences to grade only those questions answered, with the timer turned on. When they save their score it will show the timer information, number of questions answered, with the date and time the work was done.
