In any key there are 7 main chords - chords 1 through 7. With these chords you can play any song in any key.
The 7 main chords in the Key of C on piano.
In the 7 chords there are three types of chords. Major, Minor and Diminished.
First thing is to learn how these three chord types Major, Minor and Demineshed are built.
How to build a Major chord on a piano.
How to build a Minor chord on a piano.
How to build a Diminished chord on a piano.
Here again are the finger shapes for the 7 main chords in the Key of C on the piano.
its easy to see that the chords are Major, Minor, Minor, Major, Major, Minor and Demineshed.
Also notice that I call the first chord I play a 1 chord instead of a C chord.
The 1 chord = C the 2 chords = D the 3 chord = E the 4 chord = F the 5 chord = G the 6 chord = A and the 7 chord = B
And last notice that the 1 chord is Major, the 2 chord is Minor, the 3 chord is Minor, the 4 chord is Major, the 5 chord is Major, the 6 chord is Minor and the 7 chord is Demineshed.
Now that this music theory is in your head its a great time to check out our diatonic harmony section to see why we changed the chord names to numbers.
On Guitar it's really easy to play all seven chords.
Here are the finger shapes for 7 chords in the Key of G on the guitar. The same guitar chord shapes apply to all keys. If you learn these 7 shapes you will be able to play any song in any key.. (and its really only 5 chord shapes!) This was by far the best guitar lesson I ever got. I'm so thrilled to pass it on.
The diatonic harmony section also works for guitars and all western tuned instruments. See why we changed the chord names to numbers.
