Hey David! I picked up your lesson a week ago, the major pentatonic lesson,
http://www.guitarmasterclass.net/solo-guit...or-pentatonics/
and you said you change the key of the scale as the chord changes. If I am just jamming to a different chord progression, am I supposed to change the key everytime the chords change? Or if I stayed with the same key of the scale as the chords change, would it still sound good or out of place?

and how does a major pentatonic scale fit over a maj7 chord if the formula is 1 2 3 5 6?
sorry, probably a stupid question but I need clarification haha

Thanx,

Alex

Hi Alex, glad you are learning!
These are great questions.

As you said, a Major pentatoniic is a 5 note scale that is made of a root, Maj 2nd, Maj3rd, 5th and Maj6th.
That means that it will work over any key or chord that includes these 5 notes.

If we take a Maj7 chord, these are the notes we have:
Root, Maj3rd, 5th and Maj7th. These four notes don't clash with the notes of the Major pentatonic scale, which means that you can use it!

You can also use the Major pentatonic as a substitute to any scale that contains the 5 notes mentioned earlier.

Does that help?

yes the exact answer I was looking for. Thank You David! It all makes sense now!
