Most things you should know about chord extensions & suspensions right here!

Excerpt from the original

So I wrote this long ass 2-part post about chord extensions in a post that is probably buried soon and I thought it contains a lot of information that I would have loved to know myself years ago when I started about chord extensions. There is a lot of information to absorb so I recommend bookmarking and coming back to this, honestly. **Suspensions:** Only two suspensions really exist: sus2 and sus4. These two are essentially saying "play the ninth / eleventh, do not play the third". Technically, sus6 also exists, but I don't think beginners should worry about that.
