Eigenvalues and Musical Instruments
Most musical instruments are built from physical systems that oscillate at certain natural frequencies. The frequencies are the imaginary parts of the eigenvalues of a linear operator, and the decay rates are the negatives of the real parts, so it ought to be possible to give an approximate idea of the sound of a musical instrument by a single plot of points in the complex plane. Nevertheless, ...
متن کاملOptimal electronic musical instruments
0377-2217/$ see front matter 2010 Elsevier B.V. A doi:10.1016/j.ejor.2010.03.001 E-mail address: [email protected] For many musical instruments, a musician depresses various combinations of keys in order to play the notes in the instrument’s range. For traditional (or acoustic) instruments of this type (e.g., woodwinds and most brass), the ways in which the combinations of keys can be assigne...
متن کاملEmotions of Musical Instruments
This paper describes a research regarding emotions of musical instruments. The goal is to find out whether it is possible to alter a communicated emotion to a listener by using various musical instruments. These instruments are the piano, marimba, alt sax and cello. After performing an experiment clear differences are visible, especially on the emotions joy and sadness.
متن کاملVirtual Musical Instruments
The virtual musical instrument is an interface that allows users to simulate a musical instrument by printing a template on a sheet of paper, placing it in view of the webcam of their laptop, and running the console application. The user then ’plays’ the virtual instrument as if it were a real one, and appropriate music is generated. This is achieved by calibration of the template, detecting th...
متن کاملMusical instruments parametric evolution
This paper presents a study on the evolution of the perceptually most important parameters of musical instrument sounds as a function of the most important playing styles, namely the pitch and intensity. The main parameter to change when varying the intensity is the spectral envelope, and this change can be modeled with a spectral deviation, which in turn is modeled by an asymptotic exponential...
