Early classical guitar recordings

Early recordings for the classical guitar had often have a low or limited audio quality since recording technology was just in its beginning phases, with the earliest known guitar sound recorded in either 1853 or 1854 recorded the phonautograph by Édouard-Léon Scott de Martinville. The phonautogram features a snippet of Adolphe Giacomelli playing a few notes on guitar, though it is unintelligible as a result of the recording’s brevity and low quality.
