He brought in the instrument to Great Britain during his tour in 1843. The banjo gained its name as an accompaniment of United States music during the First World War. Four-string banjo There are three major types of four-string banjos plectrum banjo, tenor banjo, and cello banjo. The plectrum banjo is just like the regular banjo but it does not have a short drone string. Windsavers are valves used in instances wherein two reeds are in the same cell and there is frequent unnecessary air passage through the non-playing reed. The cover plate protects the reed-plates. This could be made of wood, plastic, or metal. The two types of cover plates are those with the traditional open design and those with enclosed designs. The Clarinet is usually wooden and vertically played. It has a wider bore which has a single reed and this, when activated, vibrates against a removable mouthpiece. Traditionally, the wood used is granadilla wood from South America, Africa, or Asia. Nowadays, it is most common as a B-flat clarinet which is about sixty centimeters in length. The bell is then hollowed out to be conical with the goal of increasing volume and sound production. The reed is made of cane. This cane is folded and attached to a short tube called staple which is placed in the wooden pipe s top. Access to the high notes comes with enormous difficulty because of the lack of reed control of wind capped instruments. Unfortunately, the Tutmarc s bass guitar did not become popular in the market. At the time of 1950 s, the first electric bass, called Fender Precision Bass, that was in mass production was created by Leo Fender. Its body design was contoured and its edges were beveled. In 1953, the Gibson Guitar Corporation put the electric bass with a violin shape and an expandable end pin on market. It is dominant in Hindustani classical music and has been around starting from the Middle Ages. It uses sympathetic strings which is common in Indian musical instruments. It also has a gourd resonating cavity and an extensive hollow neck. The sitar came into the western musical industry when Pandit Ravi Shankar used it in his works.
