Theoretical key the signature this leads to a key whose key signature has an additional sharp. A piece in C that performs this modulation would lead to the theoretical key of G major, requiring eight sharps, meaning an F in place of the F already present. To write that passage with a new key signature would require recasting the new section using the enharmonically equivalent key signature of A major. An example of such recasting is Claude Debussy's "Suite bergamasque": in the third movement "Clair de lune" the key shifts for a few measures from D major to D minor (eight flats),

The more he worked with the music, the more recalcitrant the music became and the more he hated it. "Contrastes" finally found its way into the Concert Fantasia.
