Composer and guitarist Giovanni Piacentini joins us today with guitar in hand and an enthusiasm to share with us one of Bach's most surprising moments. 

Bach's "Prelude, Fugue and Allegro" is designated for lute or harpsichord. Classical guitarists have long enjoyed the work, which is successfully adapted to the guitar. Near the end of the prelude, Bach takes us down an unexpected path, then gives us a thoroughly strange chord -- Giovanni's moment of Bach today. 

We discuss two normal ways that this chord could have progressed. But as Giovanni says, "Bach isn't normal!" Instead he takes on a wild trip before returning to the peaceful home key.
