Over the past twenty years, the front ensemble or pit has become an integral part of modern marching band and drum corps. This section of percussion is crucial to the entire production by a group. The pit creates an added effect when properly incorporated into a band. The purpose of this experiment is to discover the best technique to mic a marimba for the Woodland High School front ensemble. The front ensemble, also known as the pit, has struggled for the past three years to find the best technique for marching competitions, or inside for rehearsals. The study is important to society, especially those who attend or have connections to Woodland High School, because by attending competitions with the most advantageous microphone technique for the pit would create and opportunity for the marching band to defeat more opponents, and possibly win more awards. The study allows the pit to utilize the best technique to define the sound and amplify the most precise and clearest sound through the sound system. The study not only has importance for Woodland but for other high schools within the area because it enables other pits to replicate the experiment to find the best microphone technique to allow the other pits to also have the best microphone technique on their marimbas, or other mallet instruments. As previously mentioned, this experiment could create the opportunity for other marching bands to win more awards, and have a successful pit.
A microphone is a device that changes sound waves to electric signals (Terms and Definitions). There are two types of microphones - condenser and dynamic (Shambro). Condenser microphones are mainly found in studios (Shambro). Condenser microphones have a greater frequency response, along with a greater transient response (Shambro). Condenser microphones have the loudest sound output (Shambro). There are two types of condenser microphones – large and small diaphragms (Shambro). Large diaphragm condenser microphones (LDM) are used for vocals and instruments with “deep” sounds. The LDMs warm up a sound while small diaphragm microphones (SDM) are used for a wide frequency range, while the SDMs have the best transient response and are used for recording strings, or concerts. Dynamic microphones differ in the facts that they are more rugged in sound quality, resistance to moisture, and abuse (Shambro). Therefore, dynamic microphones have a lower frequency response than dynamic microphones, and also can withstand high sound pressure levels (Shambro).
Different pick up patterns are also crucial when determining what microphone to use in a set up. Omnidirectional microphones pick up...
