Minor seventh flat five chord

A minor seventh flat five chord, also known as a half diminished seventh chord, is composed using a root/1st, minor 3rd, diminished 5th and minor 7th (or R/1-♭3-♭5-♭7) intervals played simultaneously. Generally written as Cmi7(♭5), C∅ or C-7(-5), it is good practice to simply use an uppercase C with lowercase letters mi followed by a super scripted 7(♭5) to represent it in writing (ie: Cmi7(♭5)).

The minor seventh flat five chord is built upon the seventh degree of the harmonized major scale (tetrads) and possesses an extraordinary drive towards root resolution. The tonality of a minor seventh flat five chord is dissonant, unstable and unresolved.
