Google’s animated Doodle today pays tribute to the accordion, celebrating its 197th anniversary since its patent was granted in 1829. Known for its free-reed instrument with bellows, the accordion has significantly influenced various music genres, including pop, jazz, folk, and classical. Throughout the late 1800s, manufacturers in Germany increased accordion production due to its popularity among folk musicians across Europe. Its versatility is evident in its ability to create two chords from a single button, depending on the expansion or contraction of the bellows.
