Santa Cecilia Orchestra

Bach's Well-Tempered Clavier is a set of of Preludes and Fugues in every key.  Actually, Bach, being the restless soul that he was, wrote two sets of these.  Each of the "Great 48" has a unique character related to its key; for instance, the G major prelude and fugue are energetically joyful, while the E-flat major prelude and fuge has a kind of quiet melancholy, while the F minor has a kind of muscular anger.
