Tema, variazioni e fuga per organo (v2.3)

Organ piece based on the theme exposed from bar 5 to bar 19, after an introduction made with the beginning of the theme itself, followed by four variations and a fugue composed over the first half of the theme. The theme is used (with longer values) at the bass of the first variation and is harmonized with three voices in the second variation. The third variation is allowing itself more freedom and the fourth variation (bars 68-83) offer a different harmonization with five voices. So far this is my most complex piece, with a number of revisions since its first version in Oct. 2004.
