The lute originated in southwestern Asia, and by the eighth century AD was the most prominent instrument in Arabic culture. It was brought to Spain and Sicily by Muslim musicians in the ninth century, and spread further into western Europe. At that time the lute was an early form of the Arabic oud, and had a half-melon-shaped body with a wooden soundboard, a neck with a fretless fingerboard, and four courses (pairs) of strings which could be tuned with pegs in a bent-back pegbox. The instrument was played with a pick.
By the second half of the 15th century, string technology had advanced, expanding the lute’s range to three octaves upon 6 courses. It was now plucked with the fingers of the right hand, and frets were tied onto the fingerboard in order to prolong the sustain of the fretted strings. This was now an instrument practical for performing polyphonic music and accompaniments. By the 16th century, lute music had begun to be written down in tablature which was specific to the instrument. Baldesar Castiglione wrote in his book “The Courtier” (1528) that the lute had become the most favored instrument among courtiers.
Over the next 250 years, much of the finest instrumental music was written for it, including lute solos by Francesco da Milano, John Dowland, Denis Gaultier, and Silvius Leopold Weiss. During the late 16th and 17th centuries, players and luthiers experimented with adding more bass strings (up to 14 courses, 27 strings) and different ways of tuning the fretted strings, creating the baroque lute and long-necked theorbo. This made the lute a more demanding instrument to play, and as a result, many noblemen, including the French king Louis XIV and the English king Charles II, chose to study the five-course (nine strings) baroque guitar instead, leaving the lutes to be played by professional musicians.
Since the lute remained popular as a solo and ensemble instrument over several centuries, its notated repertoire went through the renaissance, baroque and classical styles. I personally have enjoyed studying and performing the music from all these periods. To me what is most special about the lute is the quality of its music, which is conveyed by the fingers of both of the player’s hands, in constant direct contact with the strings, the very source of its beautiful sound.
