The Lydian Modal Scale

The Lydian scale is an organization of pitches encompassing the Lydian Mode. If you are looking at the piano, it would be all the white notes from F to F. The pattern of tones are as follows:

Tone, tone, tone, semitone, tone, tone, semitone 

The order is in reverse for the descending scale. 

Listen to this Lydian scale and then repeat the recording to sing along. Notice where the tones and semitones fall.

T = Tone (Whole Tone)

ST = Semitone
