The Half-Diminished arpeggio contains four notes, all derived from the Locrian Mode. These notes are:
Root – Flat Third – Flat Fifth – Flat Seventh
So, for a Cm7b5 chord, these notes would be:
C – Eb – Gb – Bb
Notice how the Half-Diminished Arpeggio is only one note different than the Minor 7th Arpeggio, we’ve added a flat 5th compared to the perfect 5th with the Minor chord. Knowing this will not only raise your theory chops, but it also makes it easier to learn these fingerings on the guitar. Just take any Minor 7th Arpeggio, lower the 5th by one fret, and voila, instant Half-Diminished Arpeggio.
Each fingering is presented on a C Half-Diminished arpeggio, but make sure to practice these in all 12 keys so that you learn you neck, as well as take these fingerings into every possible spot on the neck.
