The five notes of the <em style=”font-family: inherit; font-size: inherit;”>major pentatonic scale are the root, 2nd, 3rd, 5th, and 6th degrees of the major scale (the 4th and 7th scale degrees are left out). The minor Pentatonic scale is the root, flat 3rd, 4th, 5th and the flatted 7th
Major A scale A, B, C#, E, F#. The pentatonic scale for A is a,c,d,e & g, then back to the root a.
Does that help?
