Does a 7th or 13th major or minor scale exist?

Maybe you are thinking of a Dominant 7th scale? If that's the case, then yes. Just play your normal major scale, but flat the seventh.

No such thing as a "13th scale". I kind of think that would be a redundant idea. There are only seven notes in a scale, as per a major key.

I suppose to get a "Minor 7th Scale" you could just flat the 2nd. But what is the point? That would be the same as the relative Major Dominant 7th.

Rock on!

well a 7th scale would be a dimished scale... and the 13th=6th so that would be aeolian scale.

Negative EMB. You have a flat 3rd, 5th and 6th in a Diminished scale. The seventh doesn't change... For example, C Diminished would be: C, D, D#, F, F#, G#, (A) and B. Anyway, that is an eight note pattern if you choose to include the natural 6th. Unless you meant something else.

Rock on!

Do you mean "the seventh degree"? That would be the Locrian scale. If you take C Major, the seventh mode would be B Locrian.

Locrian is also known as "half dimished". Also, the 5th degree in a major key is also the relative Major 7th. So in the key of C Major, the dominant 7th would be G Dominant 7th.

Rock on!
