Suspended fourth chord

A suspended fourth chord is composed using a root/1^st, perfect 4^th and a perfect 5^th (or R/1-4-5) intervals played simultaneously. Generally written as C^sus4 or C^sus, it is good practice to simply use an uppercase C with a super scripted ^sus4 to represent it in writing (ie: C^sus4).
