The Neapolitan major scale starts with a half step and flat 2nd degree, derived from the Neapolitan chord in classical harmony.

In this key the signature has 5 flats (B♭, E♭, A♭, D♭, G♭). Db major uses all five black keys of the piano, placing the hand naturally on the raised keys and creating a legato, connected feel. Modern R&B and neo-soul producers often write in Db because keyboard players find the five-flat hand position physically comfortable for extended improvisations.
