Acústica musical: a flauta transversal e as figuras de Chladni.

Abstract

This work aimed to bring interdisciplinary points in the relations between the Physics and Music, through the study of sound waves, seeking textual coherence and mathematics, in order to make possible the applicability of concepts relevant to the study of the formation, construction and operation of musical instruments, with an emphasis on transverse flute. Taking as a starting point a brief history of the relationship between Science and Music, we seek to study the nature of the waves, conceptualizing, applying and introducing mathematical properties, necessary for the development of the work. We present, didactically, properties belonging to the study of sound tubes, making a path that addresses the construction of musical scales, to finally discuss the construction and operation of the transverse flute. We also had the possibility to reproduce the experiment known as Chladni's Figures, which are figures that emerge on surfaces when they are set to vibrate at certain frequencies with numerous possibilities of vibration, each corresponding to a specific frequency of the sound, producing drawings of different complexities. These are actually a two-dimensional visualization of sound waves. The research has a theoretical character that, comprehensively, sought analysis in extensive literature (textbook and magazine articles) and provided a clear and objective text.
