A lot of times my students will learn box 1 (and maybe box 2) of the pentatonic scale really well…
But then when it comes to boxes 4 and 5… not so much.
There’s nothing wrong with boxes 1 and 2, and they will be your bread and butter. But there are times when you might want to see the boxes in a different way.
And when you use interval patterns, you will see that box 4 is equivalent to box 1, while box 5 is equivalent to box 2!
