Traditionally, key signatures are merely used to simplify notation, not to 
indicate the key and scale. Harmonic minor is rarely getting such a key 
signature, and it is not possible to have a single key signature in melodic 
minor for the variable scale degrees.

Non-standard positions appear in Turkish and Persian music, where they can be 
microtonal accidentals. In Turkish music, the name of the makam is typically 
written over the key signature. In Arabic and Bulgarian music, one may not 
write a key signature.
