Relative Minor

Am is the relative minor of C. It shares the same key signature and notes but has a different tonic center, creating a more somber mood.

Diminished Function

The B° chord contains a dissonant tritone interval. This creates a strong pull and a feeling of tension that naturally resolves back to the tonic (C).
