The xylophone (from Ancient Greek ξύλον (xúlon) 'wood' and φωνή (phōnḗ) 'sound, voice'; [1] [2] lit. ' sound of wood ' ) is a musical instrument in the percussion family that consists of wooden bars struck by mallets .
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.
Abraham Bloemaert playing a bagpipe.. A musical instrument is a device created or adapted to make musical sounds.In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument.
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]
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 ...
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.
Psychophysics quantitatively investigates the relationship between physical stimuli and the sensations and perceptions they produce. Psychophysics has been described as "the scientific study of the relation between stimulus and sensation" [1] or, more completely, as "the analysis of perceptual processes by studying the effect on a subject's experience or behaviour of systematically varying the ...
