Minor-major ninth chord

A minor/major ninth chord is composed using a root/1^st, minor 3^rd, perfect 5^th, major 7^th and major 9^th (or R/1-♭3-5-7-9) intervals played simultaneously. Generally written as Cmi^(MA9) or C-^(maj9), it is good practice to simply use an uppercase C, the lowercase letters mi followed by super scripted uppercase ^(MA9) to represent it in writing (ie: Cmi^(MA9)).
