Ace-
There are alot of people out there that are very musically inept when it comes to theory, make sure that when you put "Key: A (minor7th) that you know that there is a difference between an Amaj(min7) and an Am7. The seventh is a simple dominant seventh in minor chords, it's the third that is minored (obviously). Now you probably should change that capital A to a lowercase a, to clear up the confusion, because it sounds as if you mean to say that the seventh is minored (and to those who don't know their ****, in the Aeolian mode the 3,6,[U]7[/U] are flat)
Also, I'm curious as to why you chose to end on the 13th (F# in the key of A) in that instance. If you're demonstrating how to arpeggiate the 7th chords, adding a 13th at the end is not the way to go. If you're teaching the Charlie Parker Method, a style in which the 9th, 11trh, and 13th are very prominent, it's a little bit different, but please, It's one of my pet peeves, stay within the bounds of the musical chord structure when you say you're going to!
