Dominant thirteenth sharp ninth chord

A dominant thirteenth sharp ninth chord is composed using a root/1^st, major 3^rd, perfect 5^th, minor 7^th, augmented 9^th and major 13^th (or R/1-3-5-♭7-♯9-13) intervals played simultaneously. Generally written as C^13(♯9) or Cdom^13(♯9), it is good practice to simply use an uppercase C followed by a super scripted ^13(♯9) to represent it in writing (ie: C^13(♯9)).
