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),
Bergamasque Prealps following way: The Bergamo Prealps stretch between Lake Como (west) and Lake Iseo (east).
