The Techniques for the Use of Aluminum to Make an Acoustic Lute's Sound Box

Abstract

The research objective was to study techniques for the use of aluminum to make an acoustic lute's sound box. The study was conducted by studying related literature and using aluminum as a material instead of wood to make the sound box. The research results revealed that the researcher used aluminum, a material that is resistant to weather conditions and corrosion, hardly broken, heat-resistant, and lightweight, to make Northeastern acoustic lute’s sound box to replace the original material, wood. It was made by taking aluminum in a circular concave front with a diameter of 30 centimeters to cover with veneer, resulting in the shape of the sound box. The length of the Northeastern acoustic lute from the front to the heel is 75 centimeters while the neck of the string instrument is 45 centimeters long, creating the Northeastern acoustic lute with standard size. The researcher then evaluated the sound quality of the Northeastern acoustic lute that uses aluminum to make the sound box. It was found that the quality of sound has a clear resonance and radiate sound due to the clear lute sound box made of aluminum. This serves to resonate and amplify the audio signal. In addition, the researcher has determined that the Northeastern acoustic lute using aluminum to make the sound box has the major scale and can be played with Northeastern folk music band and western music band. As a result, the Northeastern acoustic lute using aluminum to make the sound box is durable to use and has very good sound quality, which is a good source of sound, regarded as a new innovation in Northeastern folk music.
