Melodic Minor Mode 6: Half-Diminished Scale Notes in 12 Keys

This reference chart lists notes of the Half-Diminished scale for every root note. 1 chart covering all 12 keys.

Half-Diminished scale is the 6th mode of Melodic Minor and its degrees formula is: 1-2-b3-4-b5-b6-b7.

I've included one more key, totalling in 13 keys. A# and Bb are enharmonically equivalent keys with same amount of sharps and flats (6). So they have sort of a parity—they are both valid keys. The choice between the two is a matter of notation convenience or convention in a given musical context.
