Inganni in Girolamo Frescobaldi’s "Capriccio sopra Ut, Re, Mi, Fa, Sol, La" and "Capriccio sopra La, Sol, Fa, Mi, Re, Ut"
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.
