A dominant thirteenth sharp ninth chord is composed using a root/1st, major 3rd, perfect 5th, minor 7th, augmented 9th and major 13th (or R/1-3-5-♭7-♯9-13) intervals played simultaneously. Generally written as C13(♯9) or Cdom13(♯9), it is good practice to simply use an uppercase C followed by a super scripted 13(♯9) to represent it in writing (ie: C13(♯9)).
