The minor seven flat five chord consists of four notes taken from the major scale of the same letter name. These notes are the first (1), flattened third (b3), flattened fifth (b5) and flattened seventh (b7) of the major scale, so the chord formula for the minor seven flat five chord is:
Notice that the minor seven flat five chord is simply a minor seventh chord with a flattened fifth, e.g., F#m7 F#m7b5. Another way of creating the same chord is to add a minor 7th interval to a diminished triad; sometimes this chord is called half diminished (ø) chord, e.g., F#ø. Arpeggio patterns and inversions of the F#m7b5 chord are shown here.
*The 1st inversion of the minor seven flat five arpeggio is identical to the minor sixth arpeggio pattern previously outlined. Therefore all the notes of a minor sixth arpeggio pattern are the same as the notes of a m7b5 arpeggio pattern located a minor 3rd below.
Example 143 uses the F# minor seven flat five arpeggio pattern with all inversions.
