A dumb question about the minor pentatonic
« on: August 10, 2018, 09:13:47 am »
Morning everyone

I'm just thinking about the minor pentatonic scale in relation to the major scale. I get that it's has the tricky notes removed - 2nd and 6th, and I understand that the 3rd is flat because that's what makes it minor but why is the 7th flat?

I've had a bit of a Google but can't find the answer. Can anyone school me up?

Thanks
G

Sounds like a good question, Gareth :)  Actually all questions are good questions  ;)

I can't offer an answer, but thinking about it have you compared the notes with the C maj pentatonic?  I understand that A is the related minor in the key/scale C maj.  Notes are the same, just different root note.  Maybe that might help to get more understanding?  Or maybe make it worse.  Sorry if the latter  ;D

It’s not quite like that, the removed notes are different also!
This will either explain it or get you more confused!

I'm going to go with more curious rather than confused, Darrell.

If consider Am Pentatonic and C pentatonic then I see the notes are the same but the intervals are named differently.  I am looking at playing the scales over frets 5-8. Am being the relative of C maj I guess explains why the notes are the same. 

A next step for me could be to look into intervals and degrees and their naming.  I recall this is in the PMT book.  I have also started with the Music Theory lessons on the new website.  Completed Module 1, including the test.  Have done module 2 but not yet the test.  Then need to payup and do module 3.  Eventually the interval theory will be the next topic of study :)  Till then I shall not think further on this question.

The minor pentatonic cale [ 1, ♭3, 4, 5, ♭7 ] contains five notes that are a subset of the minor (aeolian) scale
which is [ 1, 2, ♭3, 4, 5, ♭6, ♭7 ].

The major pentatonic contains five notes that are a subset of the major (ionian) scale.

Thanks Richard

Would I be on the right track, saying that the b3 is flat on the minor scale because the step between the (skipped) 2 and 3 notes is a semi-tone?

Thanks guys i think i might have it. Many times I've heard the pentatonic described as the major scale with the tricky notes removed. That's why i wondered why the 7th was flat because its not flat in the major scale. But i take it that the minor pentatonic is not the major scale with the tricky notes removed its the minor scale with the tricky notes removed and the seventh degree of the minor scale is flat. I've not looked at the minor scale yet or the (major pentatonic).

Am I getting it?

Yes

That is an unfortunate slip many people speak out loud.

Justin teaches minor pent first as it is so accessible and easy to make a start with.
He then teaches Major scale as it is the fundamental of pretty much everything.

But - the minor pent derives from the minor scale which is a mode (aeolian) of the major scale.
The major pent could naturally follow from the major scale (or even before it) but it is not so instinctive to use and mess around with licks etc.

So long as you know why and what you're okay.

Perfect. Thank you for clarifying I don't know what a mode is either and I don't need to right now. I was just confused as to why that seventh was flat. Now I know it's because the seventh in the minor scale is flat.

You're on the right lines, but the minor
 pentatonic scale should really be considered "the *minor* scale, with the tricky notes removed".

If you are looking at the major scale, you should compare it to the major pentatonic scale.

Cheers,

Keith
