So is this like that tale, 7th chord of a 7th chord?
1. Topics of discussion
In this tutorial, we will be taking a first look at 7th chords and how you can form them. So, let’s have some fun.
2. Defining 7th chords
Seventh (or 7th) chords are easily obtained. You just take one of the four magical triads and add a variation of the seventh note of the scale the triad is a part of on top of it.
Starting from this section of the series we will be looking at chords from a different perspective and look a bit more at the chord formula based on the major triad. It will all become clear when we learn about all the seventh chords in future tutorials, this is just a heads up.
So what about these seventh chords? How many of them are there? The answer is five:
- major seventh chords, which can be notated by using the expressions maj7 or M7 after the root note (e.g. Cmaj7, CM7 etc.)
- minor seventh chords, which can be notated by using the expressions min7 or m7 after the root note (e.g. Cmin7, Cm7 etc.)
- dominant seventh chords, which are notated by using the digit 7 after the root note (e.g. C7)
- minor seventh flat five chords, which are notated by using the expressions min7 or m7 followed by (♭5) (e.g. Cm7 (♭5))
- diminished seventh chords, which are notated by using the expressions dim7 after the root note (e.g. Cdim7)
We are going to look at each and every one of these chord types starting from the next tutorial so don’t be scared…yet. Notation wise, we will by using maj7 for major 7th chords, m7 for minor 7th chords and m7 (♭5) for minor seventh flat five chords.
That about covers it for this tutorial. In the next one we will be learning about major seventh chords. See you then.
