Dominant ninth chord - Ricmedia Guitar

A dominant ninth chord is composed using a root/1^st, major 3^rd, perfect 5^th, minor 7^th and major 9^th (or R/1-3-5-♭7-9) intervals played simultaneously. Generally written as C⁹ or Cdom⁹, it is good practice to simply use an uppercase C followed by a super scripted ⁹ to represent it in writing (ie: C⁹) however it is also common to see it written as Cdom⁹.
