31. Music Machine [c.1930s] Common during a historical period Muggles call the “Great Depression,” these Music Machines were typically played by vagabonds called “hoebows.” Musicians would vigorously shake the object in time with the other musicians at fireside performances. The separate beads and shapes were made from random trinkets found by Muggles whilst traveling around the country, creating not only a unique sound, but a map of their travels.
