Tonic strains of a chamber orchestra
F. Porsche · 2006
This paper deals with the acoustic behaviour of classical string instruments. The subject to be examined with the acoustic camera is a classical chamber orchestra including two violins, one viola and one cello. First each musician was asked to play the concert pitch. This note, the a’ corresponds to 440 Hz which is equivalent to a wavelength of 75cm. Then different tones, strains and different accents were played and measured. And now the questions are: What is the way of the tonic strains in the room ? Are there maybe any sensitive spots on the surface of the instruments ? Where does the strains come from ? Are there differences between the instruments ? What about the harmonic emission of notes ? This paper should give an answer to these questions and should open the awareness for room acoustics.
