This places the higher harmonics (from the 8th harmonic up, which are closer together in pitch) in a playable range, enabling the performance of diatonic melodies. The bugle, by contrast, is only useful for performing simple fanfares and military calls (such as "Taps") in a lower range (normally only utilizing the 2nd through 6th harmonics), based on the notes of a major triad (for example, the notes B, D, and F on a bugle pitched in B). Some of the finest surviving examples of trumpets date back as far as the 1580s, and were made by Anton Schnitzer of Nuremberg. Other notable trumpet makers include the Hainlein family of Nuremberg, the Haas family of Nuremberg, the Ehe family of Nuremberg, and William Bull of London. All of these instrument makers built what are now called natural trumpets. During the period, however, these instruments were simply called trumpets. Instruments based on historical instruments are made by modern makers such as Matthew Parker, Norbert Neubauer, Graham Nicholson, Markus Raquet, Geert Jan van der Heide, Cristian Bosc and Frank Tomes as well as Adolf Egger, along with his son Rainer Egger. The natural trumpet has a mouthpiece, which is inserted into the receiver. The receiver is attached to the long tubing, called the first yard, with a short connector, called a ferrule. The first yard is connected with a ferrule to the first bow, followed by another ferrule and the second yard. The second yard is attached with a ferrule to the second bow. On the baroque trumpet, the vent holes are located at the top of the second yard, and possibly on the second bow. After the second bow are the bellpipe, the ball, the bell, garland, and bezel. The bellpipe and first yard are separated by a wood block, and over that there is a cord for binding. Notable living players of the natural trumpet include Don Smithers and Jean-François Madeuf. Living players of the Baroque trumpet include Robert Farley, Anna Freeman, Alison Balsom, Crispian Steele-Perkins, Friedemann Immer, Niklas Eklund, David Blackadder, Will Wroth and John Thiessen.
