A minor seventh sharp five chord, also known as a augmented minor seventh chord, is composed using a root/1st, minor 3rd, augmented 5th and minor 7th (or R/1-♭3-♯5-♭7) intervals played simultaneously. Generally written as Cmi7(♯5) or C−7(+5), it is good practice to simply use an uppercase C with lowercase letters mi followed by a super scripted 7(♯5) to represent it in writing (ie: Cmi7(♯5)).
