Well, there are different types of hand-breakers, as you put it. For length, it would be Daquin’s Le Coucou. For athletics, it would be Salzedo’s Ballade or Recessional. For gymnastics, it would be Salzedo’s Variations. For endurance, it would be his “(Flight)”. For sheer speed, his Whirlwind. For performance, it would be the Pescetti Sonata or the Harmonious Blacksmith. For all of the above, it would be the Sonata by C.P.E. Bach. And then there is Halffter’s Danza de la Pastora, in a class by itself.
