(Just About) Every Possible C Chord
This is a PDF file (meaning you need Adobe Acrobat Reader in order to view the file) showing almost every C chord in existence. Actually, the list is still incomplete, since there are always more extensions that can be added to basic chords (i.e., C13 can become C13-5+9, etc.).
There are similar lists like this elsewhere on the Internet, but I have found them to be full of duplicates and mistakes. I have tried to arrange the chords in a logical order to help you see the patterns of how chords are formed. I have also listed the general abbreviations found in most modern lead sheets and song books. Let me know if this list is helpful, if you find any mistakes or duplications, or if you can think of a way for me to make it even better!
