KANDUS, Alejandra; GUTMANN, Friedrich Wolfgang and CASTILHO, Caio Mário Castro de. The physics of mechanical oscillations in musical instruments: example of berimbau. Rev. Bras. Ensino Fís. [online]. 2006, vol.28, n.4, pp. 427-433. ISSN 1806-9126. http://dx.doi.org/10.1590/S0102-47442006000400004.
In this work it is discussed the wave propagation in an elastic medium, particularly along strings and the air. The basic principles of the wave propagation are presented, taking as an example case a typical instrument from the state of Bahia, well known by all Brazilians, the berimbau.
Keywords : mechanical oscillations; musical instruments; berimbau.
