What is a "chord system?"
If there is one truth about pop music, it's repetitive. In many cases, songs use the same exact chords, albeit in different ways. If we erased all of the individual different ways that the same chords are being used and instead boiled it down to it's barest essentials, we can call the remaining chords a chord system.
For example, after reducing both the verse and the chorus in Dead Flowers by The Rolling Stones, you are left with the D, G, and A chords. So, basically, if you know the D, G, and A chords, you can play that song.
I've got great news for you: It doesn't stop there. The funny thing is that many, many songs use the D, G, and A chords too. Isn't that interesting?
Therefore, if you know any single chord system, you can more easily approach any song that uses that same system, and there are lots of songs written on just one of the five basic chord systems. Totally rad, right?
