ex.4 - F dorian scale + major 3rd passing note

It is more common idea to add minor 3rd for major pentatonic scale to play a blues. However major 3rd also works as a passing note for minor pentatonic scale both going up north or south, I mean 4th or minor 3rd. I do like to do a combo of major 3rd to minor 3rd trill and major 7th to minor 7th trill as I played them on the video. These subtle nuance is not easy to control more than you would think, and if we listen carefully there are a lot of players actually adding these notes wether if they are blues or jazz players.
