You are losing me here. I see b7. *minor 7th, b7 or a dominant 7th* is tha t3 names for the same thing?
Ok lets take this that way, as you are aware of this in western music you have 12 notes in total. Those are:
C C#/Db D D#/Eb E F F#/Gb G G#/Ab A A#/Bb B
When you play two notes together you have the notion of intervals:
Lets take C as the root
0 semitones - > C-C Unison (no interval)
1 semitones - > C-C# minor 2nd
2 semitones - > C-D major 2nd
3 semitones - > C-D# minor 3rd
4 semitones - > C-E major 3rd /diminished 4th
5 semitones - > C-F perfect 4th
6 semitones - > C-F# augmented 4th / diminished 5th
7 semitones - > C-G perfect 5th
8 semitones - > G-G# augmented 5th / minor 6th
9 semitones - > G-A major 6th
10 semitones - > G-A# dominant 7th / minor 7th
11 semitones - > G-B major 7th
12 semitones - > C-C octave
so you have these names for intervals. Lets check mixolydian:
you have
1 2 3 4 5 6 b7
so you have here:
root / major 2nd / minor 3rd / perfect 4th / perfect 5th / major 6th / minor 7th
minor 7th is also called dominant 7th.
Hope this cleared things a little. I am waiting for your questions about this.
and also in classical music notation you use numbers to imply these notes so:
b6 is a minor 6th b7 is a major 7th...
