This is a very unique and musically-themed wall clock. Instead of traditional numbers, the clock face is designed with the circle of fifths, a concept from music theory that organizes keys according to their relationships. 
The clock is divided into 12 segments, each labeled with a musical key:
C, G, D, A, E, B, F♯/G♭, D♭, A♭, E♭, B♭, and F.
The outer casing of the clock is a sleek black, complementing the colorful inner face.
This is a stylish and educational clock that would be perfect for a music studio, classroom, or the home of a music enthusiast!
