The term xylophone may be used generally, to include all such instruments such as the marimba, balafon and even the semantron. However, in the orchestra , the term xylophone refers specifically to a chromatic instrument of somewhat higher pitch range and drier timbre than the marimba , and these two instruments should not be confused.
It has been proposed that music synthesizers that perform computation, and/or that work by recording and playback of sound samples, or the like, be referred to as quintephones. This class of instrument includes electrophones as a special case. [1]
Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [1] [2] [3] psychophysics, [4] organology [5] (classification of the instruments), physiology, [6] music theory, [7] ethnomusicology, [8] signal processing and instrument building, [9] among other disciplines.
Psychoacoustics is the branch of psychophysics involving the scientific study of the perception of sound by the human auditory system.It is the branch of science studying the psychological responses associated with sound including noise, speech, and music.
The definition of sound, simplified, is a hearable noise. The tree will make a sound, even if nobody heard it, simply because it could have been heard. The answer to this question depends on the definition of sound. We can define sound as our perception of air vibrations. Therefore, sound does not exist if we do not hear it.
The psychology of music, or music psychology, is a branch of psychology, cognitive science, neuroscience, and/or musicology. It aims to explain and understand musical behaviour and experience , including the processes through which music is perceived, created, responded to, and incorporated into everyday life.
The criteria for classifying musical instruments vary depending on the point of view, time, and place. The many various approaches examine aspects such as the physical properties of the instrument (shape, construction, material composition, physical state, etc.), the manner in which the instrument is played (plucked, bowed, etc.), the means by which the instrument produces sound, the quality ...
Schaeffner believed that the pure physics of a musical instrument, rather than its specific construction or playing method, should always determine its classification. (Hornbostel–Sachs, for example, divides aerophones on the basis of sound production, but membranophones on the basis of the shape of the instrument).
