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.
