Prelude & Fugue No 22, from the Well Tempered Clavier, v.1 (Tranquilla)
The mysterious Prelude and Fugue in B-flat minor BWV 867 ?is special in that its fugue has five voices, has a leap of a minor 9th, and concludes with a hyperstretto (remember the theory class you slept through), the overlapping of ALL five voices offset by only one note. This seven minute work of genius beautifully arranged by Jim Tranquilla of the iTromboni ensemble is appropriate for advanced performers. -the publisher
