A key signature fits a major key and its relative minor. Find which one a melody is in from a raised 7th and from the note it ends on.

A raised 7th points to the minor

A B natural, an ending on C

Three flats fit E flat major or C minor. A raised 7th of the minor key (here B natural) and an ending on its key note point to the minor key: C minor.

Quick check

A melody has four sharps, some B sharps, and ends on C sharp. Which key is it in?
