A dominant thirteenth flat ninth chord is composed using a root/1st, major 3rd, perfect 5th, minor 7th, minor 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)).
