## The `compareintervals` module

Here is a minimal lesson file:

    header {
        countin_perc = compareintervals
        title = "Compare intervals"
    }

This file will make an exercise that ask you to compare harmonic intervals. And since you do not say which intervals, it will ask for all intervals from a small second up to a major tenth.

`first_interval_type`, `second_interval_type`

  Let you select if the intervals you are asked to compare should be a melodic or a harmonic interval. The default value is `melodic`. Possible values: `harmonic` and `melodic`.

          first_interval_type = melodic
          second_interval_type = harmonic

  Modules: `compareintervals`.

`first_interval`, `last_interval`

  Select which intervals to select from when creating the questions. This variable should be defined the same way as ask_for_intervals_0. If these two variables are not defined, then the user will be able to select which intervals to practise from the Config page of the exercise.

  Modules: `compareintervals`.
