The Portuguese guitar most diffused today has undergone considerable technical modification in the last century (dimensions, mechanical tuning system, etc.) although it has kept the same number of courses, the string tuning, and the finger technique characteristic of this type of instrument. The Portuguese Guitar is a descendant of the
Medieval citole, based on evidence of its use in Portugal since the thirteenth century (then known as 'cítole' in Portuguese) amongst
troubadour and minstrel circles and in the
Renaissance period, although initially it was restricted to noblemen in court circles. Later it became popular and references have been found to
citterns being played in the theater, in taverns and barbershops in the seventeenth and eighteenth century in particular. In 1582,
Friar Phillipe de Caverell visited Lisbon and described its customs; he mentions the Portuguese people’s love for the
cittern and other musical instruments. In 1649 was published the catalogue of the Royal Music Library of
King John IV of Portugal containing the best-known books of cittern music from foreign composers of the sixteenth and seventeenth centuries, in which the complexity and technical difficulty of the pieces allow us to believe that there had been highly skilled players in Portugal. (1910) The angel playing the cittern (c.1680), a sculpture of large dimensions in the
Alcobaça Monastery, depicts in detail the direct ancestor of the Portuguese guitar. In the first half of the eighteenth century,
Ribeiro Sanches (1699–1783) had cittern lessons in the town of
Guarda, Portugal, as he mentions in a letter from
St. Petersburg in 1735. In the same period, there is other evidence to the use of the cittern alluding to a repertoire of sonatas, minuets, etc. shared with other instruments such as the harpsichord or the guitar. Later in the century (c. 1750) a new type of cittern, the so-called
English guitar made its appearance in Portugal. By 1786 those made by Simpson, an English luthier, became highly popular, and it was noted that he could also provide reliable nickel-silver strings. There was a type of cittern locally modified by German, English, Scottish and Dutch makers and enthusiastically greeted by the new mercantile bourgeoisie of the city of
Porto who used it in the domestic context of
Hausmusik practice. This consisted of the "languid Modinhas", the "lingering Minuets" and the "risqué Lunduns", as they were then called. The English guitar disappeared as a separate instrument by the mid 19th century in Portugal as elsewhere, but its influence on the subsequent Portuguese guitar can be seen in terms of the watch-key tuning system, size, stringing with 6 strings and tuning - see description of the
afinação natural (natural tuning) under Tuning below. Especially from the middle of the 19th century, the Portuguese guitar as a separate instrument developed from the various earlier types of citterns came into fashion by its association with the Lisbon song (
fado) accompaniment. The last detailed reference to the cítara appeared in 1858 in
J.F. Fètis' book
The Music Made Easy. The Portuguese translation includes a glossary describing the various characteristics (tunings, social status, repertoire, etc.) of both cittern and "English" guitar of the time. Gradually the Simpson design was transformed by Portuguese luthiers, with a wider body, longer scale length, and a wider fingerboard, made more manageable by using a large radius, rather than a flat fingerboard. The Portuguese guitar is used for solo music (
guitarradas) as well as the accompaniment, which it shares with a steel strung classical guitar (
viola de fado) and occasional double bass or guitar-bass, and its wide repertoire is often presented in concert halls and in the context of classical and world music festivals all around the world. ==Models==
