The Major Scale is one of the most common types of scales. The organization of whole tones and semitones in an ascending scale are in the following order:
Tone, tone, semitone, tone, tone, tone semitone.
This pattern will be in reverse when descending.
Listen to this major scale and then repeat the recording to sing along. Notice where the tones and semitones fall.
T = Tone (Whole Tone/2 semitones)
ST = Semitone
