Toccata
Toccatas became popular in Germany with composers such as Hans Leo Hassler who had studied in Venice with Gabrieli.  Many German Baroque organ composers wrote toccatas: Sweelinck (who was Dutch), Pachelbel, Buxtehude and Johann Sebastian Bach.  Bach wrote a Toccata and Fugue in D minor, which is one of the most famous pieces of Baroque organ music, and perhaps the most famous toccata ever written.
