The 'fantasia' (also , , ) is a musical composition with its roots in the art of
improvisation. Because of this, it seldom approximates the textbook rules of any strict
musical form.
In the
Baroque and
Classical music eras, a fantasia was typically a piece for
keyboard instruments with alternating sections of rapid passagework and
fugal texture. From the Baroque period,
J. S. Bach's ''Chromatic Fantasia and Fugue'',
BWV 903, for
harpsichord; ''Fantasia and Fugue in G minor'',
BWV 542, for
organ; and ''Fantasia and Fugue in C minor'',
BWV 537, for organ are examples. For an example from the Classical period, see
Mozart's ''
Fantasia in D minor'', K. 397 (see
Köchel) for
fortepiano. In contemporary music,
Busoni's Fantasia Contrappuntistica or
Corigliano's ''Fantasia on an
ostinato'' are examples of a fantasia.
The term also referred in the
Baroque era (more specifically British Tudor music) to pieces for viols, characteristically- though not always- alternating, in this case rapid fugal sections with slower sections in slow notes and sometimes clashing harmonies. According to the Oxford Concise Dictionary of Music's entry the instrumental fantasia was closely related in its history and form to the
motet.
Henry Purcell's fantasias are the last Baroque representatives of the breed, although
Walter Willson Cobbett, in the opening decades of the
20th century, attempted to resurrect something of this style via a competition, to which works like
John Ireland's and
Frank Bridge's phantasie-trios,
Benjamin Britten's phantasie-quartet (for oboe and strings) and other music owe their existence.
In the
Romantic period, two contradictory trends greatly affected the fantasia: one was the decline of formal improvisation as a test of the compositional technique; the other was the move by composers toward freer forms.
Chopin's ''Fantasy'' in F minor op. 49, combines various keyboard textures of the
stile brillante with the classical sonata paradigm, resulting in a work of unorthodox but sophisticated form.
Schumann's numerous 'fantasy pieces' are character works on a smaller scale, often bearing descriptive titles.
