    Acercamiento a las propiedades físicas y acústicas de dos arcos alemanes en el contrabajo
    (Universidad EAFIT, 2019) Álvarez Londoño, Juan Guillermo; Manco, Juan David
    This investigation asked if there were differences between a bow of luthier (craftsman) and a bow of Chinese manufacture, so that it was aimed at describing the physical and acoustic properties of a German Arch of Pernambuco and a Chinese German Arc. The research was conducted under a quantitative approach, with an exploratory scope and was developed in two phases: physical measurements and acoustic measurements of both arcs. Differences were found in the physical characteristics for the two arcs, while in the acoustic measurements no significant differences were found. So that the difference that can make a distinction between one arch and the other, is from the interaction and knowledge of the instrument, because from there a musician builds a large part of his sonority.
