A neck projects from the body, and strings are stretched over the neck and the body. When a player bows the strings, the strings vibrate, and the vibrations are propagated to the body. The body also vibrates for generating tones, and the resonator makes the tones loud. Thus, the bowed stringed musical instrument generates the loud tones through the resonator. Lower pitched tones require a large resonator. For this reason, the double-bass has the largest body in the violin family. A stringed musical instrument with a resonator is hereinbelow referred to as xe2x80x9cacoustic stringed musical instrument.xe2x80x9d The violin,the viola, the cello and the double-bass described hereinbefore are categorized in the acoustic stringed musical instrument.

Although other orchestra members generate tones through other musical instruments in a symphony, the other tones do not drown the tones from the acoustic bowed stringed musical instruments, and the audience can discriminate the tones of the acoustic bowed stringed musical instruments from the other tones in a concert hall. Thus, the string player appreciates the resonator for the loudness. However, the loud tones are often a nuisance to the neighborhood. The string players feel it difficult to seek a practice room.
Although the loudness is reduced to some degree with muted strings, it is impossible to keep the acoustic stringed
