A minor six-nine chord is composed using a root/1st, minor 3rd, perfect 5th, major 6th and major 9th (or R/1-♭3-5-6-9) intervals played simultaneously. Generally written as Cmi6/9 or C−6/9, it is good practice to simply use an uppercase C then the lowercase letters mi followed by a super scripted 6/9 to represent it in writing (ie: Cmi6/9).
