In the 1600's, Galileo demonstrated that the frequency of sound determines their pitch. This made brass instuments become more popular because many, if not all, of the brass instruments are played by changing the tension with the lips to make faster or slower waves to change pitch. In the late 1600's, Isaac Newton discovered and formulated the relationship between speed of sound, in a medium, and the density and compressibility of the medium. This means that the speed of the air going into the instrumenteffects the compressibility which then may alter the pitch thatis heard. French Horn The French Horn is made up of four parts.Each of these parts contribute to being able to change the pitch, and amplitude. The bell is one of the places where the instrumentalists holds the instrument up. The tubing in all, is 12 feet in length. The mouthpiece is where the instrumentalist produces sound The valves is where the instrumentalist presses different buttons to close off different parts of the horn to produce different pitches How the French Horn is Played The french horn is madefrom metal and plated sometimes with a thin layer of silver on the mouthpiece. The French horn name is called the "french horn" to distinguish itself from the English horn, even though the English horn just looks like a larger version of the Oboe. The French horn produces different pitches not only by pressing down one of the three (or four) keys, but can also by the pitch by changing the tension of the musicians lips. For example, if the musician presses their lips together tighter than usual, the note will go up the octave without pressing any keys down. The horn player also has the capability of changing the volume by blowing fast air, or slower air. The faster air will make a faster frequency which makes a louder sound. The opposite occurs if the musician blows through the instrument slowly. sources: Busch-Vishniac Ilene, Sound The World Book of Encyclopedia Chicago, World Book, Inc. 605-606Ross, Stewart L.
