Sonata in d minor [stylus fantasticus]
"The stylus fantasticus, fantastic style is especially suited to instruments. It is the most free and unrestrained method of composing, it is bound to nothing, neither to any words nor to a melodic subject, it was instituted to display genius and to teach the hidden design of harmony and the ingenious composition of harmonic phrases and fugues." [in: Athanasius Kircher, Musurgia universalis sive ars magna consoni et dissoni in libros digesta, Roma, 1650.]
