Dominant seventh sharp eleventh chord

A dominant seventh sharp eleventh chord is composed using a root/1^st, major 3^rd, perfect 5^th, minor 7^th, major 9^th and augmented 11^th (or R/1-3-5-♭7-9-♯11) intervals played simultaneously. Generally written as C^7(♯11), C7⁺¹¹ or C^-7+11, it is good practice to simply use an uppercase C followed by a super scripted ^7(♯11) to represent it in writing (ie: C^7(♯11))
