In music theory, the major seventh flat five chord is a seventh chord composed of a root note, together with a major third, a diminished fifth, and a major seventh above the root (1, 3, 5 and 7). For example, the dominant seventh flat five chord built on C, commonly written as C{M75 or CΔ5, is composed of the pitches C–E–G–B:


{
\override Score.TimeSignature #'stencil = ##f
\relative c' {
   \clef treble 
   \time 4/4
   \key c \major
   <c e ges b>1
} }

It can be represented by the integer notation {0, 4, 6, 11}.

In jazz harmony, the major seventh flat five may be considered an altered chord, created by lowering the fifth of a major seventh chord.
