The speed of sound depends on the medium the waves pass through, and is a fundamental property of the material. The first significant effort towards measurement of the speed of sound was made by Isaac Newton. He believed the speed of sound in a particular substance was equal to the square root of the pressure acting on it divided by its density:
Musical tones produced by the human voice and all acoustical musical instruments incorporate noises in varying degrees. Most consonants in human speech (e.g., the sounds of f, v, s, z, both voiced and unvoiced th, Scottish and German ch) are characterised by distinctive noises, and even vowels are not entirely noise free.
According to Danish noise and music theorist Torben Sangild, one single definition of noise in music is not possible. Sangild instead provides three basic definitions of noise: a musical acoustics definition, a second communicative definition based on distortion or disturbance of a communicative signal, and a third definition based in subjectivity (what is noise to one person can be meaningful ...
CDs became available in the early 1980s. At this time analog sound reproduction was a mature technology. There was a mixed critical response to early digital recordings released on CD. Compared to vinyl record, it was noticed that CD was far more revealing of the acoustics and ambient background noise of the recording environment. [37]
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
Some definitions refer to music as a score, or a composition: [18] [7] [19] music can be read as well as heard, and a piece of music written but never played is a piece of music notwithstanding. According to Edward E. Gordon the process of reading music , at least for trained musicians, involves a process, called "inner hearing" or "audiation ...
In musical terminology, tempo (Italian for 'time'; plural 'tempos', or tempi from the Italian plural), also known as beats per minute, is the speed or pace of a given composition. In classical music, tempo is typically indicated with an instruction at the start of a piece (often using conventional Italian terms) and is usually measured in beats ...
The tempo is the speed of the pulse. If a pulse becomes too fast it would become a drone; one that is too slow would be perceived as unconnected sounds. [2] When the period of any continuous beat is faster than 8–10 per second or slower than 1 per 1.5–2 seconds, it cannot be perceived as such. [2] "Musical" pulses are generally specified in ...
