Major ninth sharp eleventh chord

A major ninth sharp eleventh chord is composed using a root/1^st, major 3^rd, perfect 5^th, major 7^th, major 9^th and augmented 11^th (or R/1-3-5-7-9-♯11) intervals played simultaneously. Generally written as CMA^9(♯11) or Cma⁹⁽⁺¹¹⁾, it is good practice to simply use an uppercase C, then the uppercase letters MA, followed by a super scripted ^9(♯11) to represent it in writing (ie: CMA^9(♯11)).
