Intrata and Passacaglia Piccola
for organ

Entrata and Passacaglia Piccola for organ was composed during 1966/1967. The Entrata presents a forceful, aggressive, and basically monophonic melodic line, divided between the manual and the pedal. The Passacaglia Piccola is constructed upon a basso ostinato consisting of seven tones. This bass line unites the various sections which go to make up the passacaglia and also supplies the musical material for the rest of the melodic lines. The ostinato motif is presented in full, in part or with alterations in organ registers. At the end of the work the Entrata returns, in a shortened and more concentrated form.
