Abstract
Contrary to the usual practice Frescobaldi used the ascending and descending hexachords as the soggetti of two separate pieces — the first and the second Capriccios from Il primo libro di capricci fatti sopra diversi soggetti et arie, in partitura (1624). The pieces are united by a common idea, such as consistent application of the inganno technique, which is rare in compositions on ut re mi fa sol la.
