<para>This exercise is one of the exercises you can use to practise intervals.
The concept is pretty simple: You press the <guibutton>New interval</guibutton>
button to play a random interval, and then you should tell what interval it
was.
</para>

<para>If you are using the buttons interface, then you can right-click on
the buttons to hear the interval they represent.</para>
