Use these song references when you identify the intervals:
2 – Happy Birthday3rd – Oh When The Saints
4 – Here Comes The Bride
5 – Twinkle Twinkle
6 – My Way
7 – Superman Theme
Octave – Over The Rainbow
These intervals are diatonic, this means that they are from the major scale (Do re mi fa so la ti de), so no sharp or flat notes.
Once you get them right straight away in every new session, move on to Intermediate Ear Training where you will integrate all the remaining chromatic intervals.
