Once you understand how chords are built finding new ones becomes really easy! It’s simply a matter of knowing your scales and where the notes lie within the scale. The major scale has seven notes if we know where they all sit the we can use them to build chords.
Similar to the above idea, when we select chords to use in song structures, we just need to use some basic rules to get us choosing the right chords for the key you’re woking in.
By applying the Tone, Tone, Semi-Tone, Tone, Tone, Tone, Semi-Tone approach and knowing that the chords on each of these notes are major, minor, minor, major, major, minor, diminished, we can find all of the chords in govern key and learn songs much quicker than we did before we had this knowledge.
I know the above might sound like an awful lot of jargon, so I’ve put together a relatively short animated video will give you a detailed understanding of how to build the major scale in any key and develop chords within that key.
Enjoy the video.
