A major seventh flat five chord is composed using a root/1st, major 3rd, diminished 5th and major 7th (or R/1-3-♭5-7) intervals played simultaneously. Generally written as CMA7(♭5) or Cma7(-5), it is good practice to simply use an uppercase C then uppercase letters MA followed by a super scripted 7(♭5) to represent it in writing (ie: CMA7(♭5)).
