CetIntervalle app for iPhone and iPad

Cet Intervalle is a quiz to learn musical intervals.

The default operation is to quiz the user on Perfect Fifths up and down from randomly selected notes and there is no time limit. Notes are selected via a pick list at the bottom of the screen which has the note names and another pick list is used for accidentals. Natural will cancel an inadvertently selected accidental.

Other intervals can be selected from the "Add Intervals" option under Settings. These include perfect unisons, fourths, fifths. octaves, elevenths and twelfths; minor and major intervals up to 13ths and augmented and diminished of same. Many of these intervals are more theoretical than practical as they are enharmonic with other intervals.

Multiple intervals can be selected. The interval selected for the question will be randomly selected from the selected intervals.

Intervals can be deleted from the selected intervals by using the edit facility under the "Selected Intervals" option under Settings. Deleting a selected intervals only unselects it from being quizzed. It can always be re-added again.

A time limit can be set up to 300 seconds in the "Misc. Settings" option under Settings. A timeout of 0 indicates no timer.
