Yes, but a Flatted 5th is the same as an augmented 4th, right?


The difference between an augmented fourth and a diminished fifth is how the altered note effects the scale that it is applied to.The note ends up being the same when you compare the two however so i can see how you may think that.
Heres an example:

Take the E natural minor scale...
--------------------------------------
--------------------------------------
-----------------------7-9-----------
-------------7-9-10-----------------
---7-9-10---------------------------
---------------------------------------

If you where to alter the scale using an augmented fourth it would look like this:

-------------------------------------
-------------------------------------
-----------------------7-9----------
-------------8-9-10----------------
---7-9-10--------------------------
-------------------------------------

as you can see, the augmented fourth produces chromatic notes on the d string.
Now here is the E minor scale with a diminished fifth:

--------------------------------------
--------------------------------------
-----------------------7-9-----------
-------------7-8-10-----------------
---7-9-10---------------------------
--------------------------------------

If you play these altered scales you can clearly tell the difference between the way that they alter there parent scale.

you will also notice that they are the same note,(A#), so you are correct in saying so.

I have heard of the "devils scale," and i am positive that it exists, but scales almost always have more than one name and i doubt that most teachers would refer to that particular scale as the devils scale. If the devils scale is based on the augmented fourth therefore it would be the fingering pattern in example 2.

Hope that helps.
