History The creation of the trombone dates back more than six hundred years. Its original design was somewhat imitated from sackbut, an Old English instrument. The term sackbut originated from the French saquer which means pull and bouter meaning push. Trompone is the Italian for sackbut and this is most probably the basis of the word trombone. Pressing one end causes the other end which is inside to come up. This end has a tangent, a metallic thin blade, which strikes the respective string. Until the player releases the key, the tangent remains touching the string and produces sound. One advantage of the clavichord over the piano is that it can perform a sound like the vibrato on string instruments. Ceremonial presentations One of the most popular rituals in Arnhem Land is the Narra ritual. Its songs are commonly accompanied by large paired sticks that are slowly beaten. Due to the towering ceremonial status of the Narra rituals, some may believe that songs accompanied by the didgeridoo are younger that Narra songs. The term harpsichord could mean any member of the harpsichord family but it particularly denotes an instrument that has the same shape as a grand piano with a triangular case. At the right, it has short treble strings while at the left are long bass strings. It is longer than the modern piano and has a sharper curve. It is also referred to as mandole and has a scale length of approximately 20 inches. The sopranino or piccolo mandolin is pitched an fourth of an octave higher than the mandolin. Mandolin styles There are six mandolin styles the Neapolitan bowlback, a-style flatback, f-style flatback, Maccaferi style flatback, solid body electric, and electro-acoustic mandolins. Oboe s structure Traditionally, oboes are made of granadilla or African Blackwood and have three sections top joint, bottom joint, and bell section. The left hand controls the 10 holes on the top joint while the right hand is used for the also 10 holes on the bottom joint. Covered with keys are two holes in the bell section.
