Ok I’m going to give you a quick video on the difference between A7 and A major 7. Very commonly mixed up and kind of an easy fix. So here it is.
The key of A is A B C# D E F# G#. 1 2 3 4 5 6 7.
An A major 7 is simply that major scale, 1 3 5 7 which is the notes of A C# E and G# and it sounds like this. *Plays A Major 7 Chord* Major 7s are jazzy. Now if I flat that last one and I go A C# E G, so I flat my 7 to a G, it becomes this *plays A (dom) 7* which is an A7, also known as an A dominant 7, right? And that’s very common in the blues. And that’s it. That’s the difference between an A7 also known as an A dominant 7 and an A major 7.
