The archlute (Spanish archilaúd, Italian arciliuto, German Erzlaute, Russian Архилютня) is a European plucked string instrument developed around 1600 as a compromise between the very large theorbo, the size and re-entrant tuning of which made for difficulties in the performance of solo music, and the Renaissance tenor lute, which lacked the bass range of the theorbo. Essentially a tenor lute with the theorbo's neck-extension, the archlute lacks the power in the tenor and the bass that the theorbo's large body and typically greater string length provide.
