A major seventh sharp eleventh chord is composed using a root/1st, major 3rd, perfect 5th, major 7th, major 9th and augmented 11th (or R/1-3-5-7-9-♯11) intervals played simultaneously. Generally written as CMA7(♯11) or CΔ7(♯11), it is good practice to simply use an uppercase C then the uppercase letters MA followed by a super scripted 7(♯11) to represent it in writing (ie: CMA7(♯11)).
