The key signature of D flat major key has five flats and Its relative minor scale is B flat min. The parallel minor scale of D flat major key is D flat minor: sometimes it is replaced by C sharp min, because D flat min that would contain a double flat in the key signature, is not often used for practical composing or arranging.
