I am watching these youtube videos where they talk about shapes of pentatonic scales.
For example, Am pentatonic scale as below:
Position 1 starts with A but ends up in C.
Bm also starts with B but ends with D in position 1.
Don't the scale have to start and end at the same root note?
All the videos start from the root on low E but end up on one note higher on the high E.
