I understand that this may be basic. I have a chorus progression (C major) I am working on, and it originally started as basically the following:
I wanted to experiment a little by added notes outside of the triad. Then I thought I would just hold the G and C notes from the I chord throughout the rest of the progression. I like the effect, but I need to know more specifically what exactly I did and how dramatically I altered the chords. Here's how it looks now:
Can you help me identify the new chords? This leads to a broader question I have been curious about. When you add a seventh, say, to a V chord, you get a V7. When you add a sixth to a V chord, you get a V6. But what about when you add a sixth and a seventh? Or a sixth, a seventh, and a fourth? Is it a game of "majority rules" regarding how to name the chord? Does the root note carry more importance than other notes?
I would be very appreciative if you could help me get to the bottom of this! Thanks!
