Hi,
Just a simple question to start understanding theory basics. No idea of theory at all.

Why 'A minor' pentatonic scale is called 'minor' if root note is 'A'?
does the question make sense?

hey there it's called minor pentatonic not because of the root but because it has a minor third (b3) in it's structure and it's made out of 5 notes (PENTA = 5). It's called A minor pentatonic, because its root note is A.

So, let's tackle A minor pentatonic - A C D E G are it's notes and the actual formula is 1 (root) b3 (minor third) 4 (perfect fourth) 5 (perfect fifth) b7 (minor seventh)

Hope this solved the problem

Thanks Cosmin, ... it really took me a while man, i didn't thought about Aminor pentatonic was based on Aminor scale (a bit silly of me )

So you apply the formula on the Amajor scale , right?

Remove 2nd - 6th and
3rd - 7th move a semitone down (b3-b7)
So you have the first position of Aminor Pentatonic

I hope this is right

Is there a formula for Minor scale? (not pentatonic)

Yes, when using a scale formula, it'll be based off the Major scale.

--

To go from Minor -> Minor pentatonic:

Natural Minor (as given by Ivan): 1 2 ♭3 4 5 ♭6 ♭7 8

Just remove the 2 and b6, that is all (Pentatonic, 'penta' = 5).

PS: We're naming it the 'Natural' Minor scale as there are different types, such as Harmonic Minor and Melodic Minor. Natural Minor is the 'regular' Minor scale.
