On the question Minor Pentatonic scale, @user37496's answer includes a circular pie chart for major pentatonic scales built on the circle of 5ths/4ths which demos the 'outside' notes of each position in the chart (see below). I don't have the ability to recreate this chart for the A minor pentatonic. Would you be willing to create a chart with Am Pentatonic at the 12 o'clock position and the 'outside' notes for each of the other positions. If I could look at both charts, side by side, I would be able to compare the similarities and differences between the two scales instantly. I think I get the gist of your explanation, but ....
To recreate the C Major chart as an A Minor chart:
- Move all the pentatonic scale names 3 positions counter-clockwise. That is, A replaces C, E replaces G, and so on. Leave the other elements of the chart -- the notes in each scale and the number of "outside" notes -- as they currently are. Only the names of the scales are rotated.
- The notes for each scale are identical, the starting note need only be changed. For example, in the C major chart, D pentatonic is given as D E F# A B. After step 1) above, these notes will correspond to the B Minor pentatonic, which is B D E F# A. This will be true for every scale -- just rewrite the given major pentatonic starting on its last note.
- The number of "outside" notes will remain as given.
There are several scales called "minor pentatonic", I presume you mean the most common "blues pentatonic". Its notes are identical to its parallel (third above) major pentatonic, thus the chart in question would look identical.
- C major pentatonic = A minor pentatonic
- G major pentatonic = E minor pentatonic
...and so on.
