can anyone tell me the relation of the pentatonic scale to the major scale? eg in the minor scale the 3rd 6th nd 7th notes are flattened? how can the notes for the Am pentatonic be determined from the Amaj or Aminor scale?
Minor Pentatonic: 1 b3 4 5 b7
Major Pentatonic: 1 2 3 5 6
But boys will be boys and girls have those eyes
that'll cut you to ribbons, sometimes
and all you can do is just wait by the moon
and bleed if it's what she says you ought to do

Well a minor scale has a b3 b6 and b7.
Minor pentatonic scales ommit 2nds and 6ths.
So minor pentatonic is a major scale without a 2nd 6th and a flattened 3rd and 7td.

The minor pentatonic exists at various points within the major scale. The ii, iii, and vi degrees of the major scale are where you can build the minor pentatonic.

Your A minor pentatonic exists at:

ii in G Major
iii in F Major
vi in C Major
Pentatonic scales are the same as their parent scale with 2 notes missing, bringing the total to 5 (hence, penta). You remove these two notes because they are a semitone (one fret) away from another note in the scale, so they want to move that way. By removing these notes, you remove any chance of these dissonances occuring, and can pretty much hit any note you want and it will sound at least ok.

theory states 1+1=2 sometimes in music 1+1=3.

I'am trying to understand this, what do you mean Amin exists at: ii in G maj, iii in F and so on? Thanks

have at look at these diagrams and it should be clear...

Major Scale

Major Pentatonic

Compare those, then do the same for minor & minor pentatonic

you can compare the formulas here...

Pentatonic substitution is one of a lot of ways to create different sounds over chords, depending on how you're treating the chord as it relates to it's parent major scale.

The approach works best over static or slow moving progressions.
I've only learnt the minor pentatonic scale and the major scale but not the major pentatonic scale which as has been explained is the major scale minus a couple of notes. Looking at the diagrams it seems the major pentatonic scale first position is the same shape as the 2nd position minor pentatonic scale in relation to the first position major scale and so on if this makes sense

Yeah, man. Those two scales are relative to each other, and are the two most important scales you'll need in music.
Cheers, it's slowly making sense. The minor pentatonic makes the most sense to me cause it usually always sounds good improvising and I can usually add a few notes outside of that scale which sometimes sound pretty good
