Pentatonics and Melodic Minor

Postby Cheap Bass Tard » Fri Dec 17, 2010 9:58 am

Is there a set of pentatonic equivalents that corresponds to the melodic minor scale the same way we have pentatonics that correspond to the standard major/minor (i.e. non-jazz) scales?

Just curious.

Good question!

Let me start out by mentioning that the Melodic Minor Scale
has the rather unique distinction of being different in it's ascending form
as opposed to it's descending form.

To illustrate this in the key of C,
when ascending it is the same as Natural Minor
with the exception of the 6th and 7th intervals being raised a semitone (half step)-

C, D, Eb, F, G, A, B, C

and in it's descending form it is identical to Natural Minor-

C, Bb, Ab, G, F, Eb, D, C

That being said,
and given that Pentatonic Scales are created from the Natural Minor and Natural Major Scales
by omitting their 2nd and 6th intervals
(leaving you with five tones, hence "Penta", with their sixth tone being the octave of the tonic),
therefore in theory...

To create a "Pentatonic Melodic Minor Scale"
(of which I have never heard but that doesn't mean it doesn't exist)
you would remove the 2nd and 6th intervals in both the ascending and descending form of Melodic Minor
leaving you with the following tones in the key of C;

Ascending-

C, Eb, F, G, B, C

Descending-

C, Bb, G, F, Eb, C

Melodic minor is different going up and coming down in classical music but in jazz it stay as melodic minor and doesn't change back into natural minor. A pentatonic scale is a 5 note scale. Pick any 5 notes and you have a pentatonic scale. Now, the most common would be the two already mentioned (major and minor pentatonic) but there are a few more and you could use the Melodic minor scale to make one (really by just raising the flatted 7th). I don't think you could differentiate that from one derived of the Harmonic minor scale since the 6th doesn't show up (unless you make up your own 5 note scale). You can play around with them. If you have a keyboard handy, just use the black keys and start on each of the different notes to see what you come up with.
