- Building for the work “Piccolo Infinito” by Massimo Scamarcio and Neal Peruffo, in occasion of the event “Illuminazione” at the Palace of Arts of Naples (PAN).
- The installation was prepared in an elevator covered with black panels. With light wood trying to lose perception of the delimitation of space, accompanied by the diffusion of reverberated sound. The recorded sound (noise of the movement of the elevator) is propagated through special speakers that vibrate the metal walls.
- We present a simple didactical approach, suitable for the students, which allows to illustrate and test some basic features of the concepts of timbre and consonance of musical sounds, in the context of western tonal music. This approach will be embedded in web documents to be remotely accessed by students and teachers. We will say that two pure sounds, separated by a given frequency interval, are consonant if their simultaneous emission produces a gratifying effect; dissonant, on the contrary, when the effect is disagreable. This gross criterion is based on psychoacoustical considerations. We know that the human auditory apparatus is able to distinguish the sounds produced by a saxophone and a clarinet when the same note with the same pitch and the same loudness is played with these musical instruments. To justify this phenomenon we simply say that this ability depends on a characteristic of sounds called timbre. But what the timbre of a sound is? Even if many papers and books have been written about this very fascinating question, we are still very far from a scientific exhaustive definition of it. The main characteristics of the timbre of sounds of a musical instrument are usually considered their harmonic content, attack and decay. In this paper we will limit ourselves to examine mostly the harmonic content, because it can be considered like a footprint of a musical sound and seems to play a relevant role in the explanation of consonance of sounds, particularly in western tonal music. In this context we will specially point out some important contributions given by H.H. Helmoltz, J.P. Rameau and by the modern psycoacoustics.
