What do these three songs have in common?
1-In a Sentimental Mood
3-Someone to Watch Over Me
The opening notes of all three songs are a construct of the Pentatonic Scale.
Check out Bobby McFerrin having fun using it with a live audience.(2009)
What a teacher!
This will take about three minutes out of your life but IMHO well worth the time.
Pass it on to any students you might have.
