A minor sixth chord is composed using a root/1st, minor 3rd, perfect 5th and major 6th (or R/1-♭3-5-6) intervals played simultaneously. Generally written as Cmi6, Cmiadd6 or Cmi(maj6), it is good practice to simply use an uppercase C then the lowercase letters mi followed by a super scripted 6 to represent it in writing (ie: Cmi6).
