A quodlibet (//; Latin for "whatever you wish" from quod, "what" and libet, "pleases") is a piece of music combining several different melodies, usually popular tunes, in counterpoint and often a light-hearted, humorous manner. There are three main types of quodlibet:
- A catalogue quodlibet consists of a free setting of catalogue poetry (usually humorous lists of loosely related items).
- In a successive quodlibet, one voice has short musical quotations and textual quotations while the other voices provide homophonic accompaniment.
- In a simultaneous quodlibet, two or more pre-existing melodies are combined. The simultaneous quodlibet may be considered a historical antecedent to the modern-day musical mashup.
The origins of the quodlibet can be traced to the 15th century, when the practice of combining folk tunes was popular. Composer Wolfgang Schmeltzl first used the term in a specifically musical context in 1544. An early exponent of the genre was 16th century composer Ludwig Senfl whose ability to juxtapose several pre-existing melodies in a cantus firmus quodlibet resulted in works such as Ach Elselein/Es taget, a piece noted for its symbolism rather than its humor. Even earlier we can find another example in Francisco de Peñalosa's Por las sierras de Madrid, from his Cancionero Musical de Palacio. However, it was Michael Praetorius who, in 1618, provided the first systematic definition of the quodlibet as "a mixture of diverse elements quoted from sacred and secular compositions". During the Renaissance, a composer's ability to juxtapose several pre-existing melodies, such as in the cantus firmus quodlibet, was considered the ultimate mastery of counterpoint.
19th century to today
The quodlibet took on additional functions between the beginning and middle of the 19th century, when it became known as the potpourri and the musical switch. In these forms, the quodlibet would often feature anywhere from six to fifty or more consecutive "quotations"; the distinct incongruity between words and music served as a potent source of parody and entertainment. In the 20th century, the quodlibet remained a genre in which well-known tunes and/or texts were quoted, either simultaneously or in succession, generally for humorous effect.
In the 16th century, an independent variant of the quodlibet named ensalada developed in Spain.
- The masses of Jacob Obrecht, which sometimes combine popular tunes, plainsong and original music.
- The last (thirtieth) variation of Bach's Goldberg Variations is a quodlibet.
- Bach's Wedding Quodlibet or Quodlibet, which is not a quodlibet by the above definition but a ten-minute procession of nonsense, jokes, puns, obscure cultural references, word games, and parody of other songs. At times, the music imitates a chaconne and a fugue while deliberately obscuring the counterpoint. It is unlike any of Bach's other works, and a few scholars doubt its authenticity, despite the fact that the sole surviving source is a fair copy manuscript in Bach's own handwriting.
