Major six-nine chord

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