🎙 The Dawn of Sound Recording

The journey of sound recording began with Thomas Edison's invention of the phonograph in 1877, a revolutionary moment in human history that enabled the recording and playback of sound. Before this, music preservation was limited to sheet music, the only method to replicate tunes across time and space. Early sound recording experiments included attaching a stylus to a vibrating object, but it was Edison's phonograph that captured the world's imagination. However, Edison was not alone in his endeavors; Edouard-Leon Scott de Martinville in France had previously made significant strides with his phonautograph, which visualized sound waves in soot but was not designed for playback. Despite its initial limitations, the phonautograph's recordings, notably of the French folk song 'Au clair de la lune,' were eventually played back by researchers, predating Edison's recordings and reshaping our understanding of the history of sound recording.
