In music, an octave is a sound interval, grouping all notes whose frequencies are between a frequency reference f and the double 2xf.
For instance: C 220 is a note whose frequency is 220Hz, so we can define one octave including many sounds, all these sounds have a frequency higher than 220Hz and lower than 440Hz.
For every octave, we can define 8 different notes: A B C D E F G A
Moreover, we can add sharps and flats: A# C# D# F# G#
To know which octave we are talking about, we give a number indicating the octave.
In the array below, an octave is an entire column plus the first note of next column.

Obviously, the more an Ocarina can play notes of this array; the bigger the number of songs it can handle.
So before buying an ocarina, check the instrument's capacity to play the notes you want to play.
Here is the video of classical music played with a triple ocarina:
