Microtonality is the use in music of microtones — intervals smaller than a semitone, also called "microintervals".It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave.
A semitone is thus made of two steps, and three steps make a three-quarter tone or neutral second, half of a minor third. The 8-TET scale is composed of three-quarter tones. Four steps make a whole tone. Quarter tones and intervals close to them also occur in a number of other equally tempered tuning systems.
Entrainment in the biomusicological sense refers to the synchronization (e.g., foot tapping) of organisms to an external perceived rhythm such as human music and dance. Humans are the only species for which all individuals experience entrainment, although there are documented examples of entrained nonhuman individuals.
Biomusic can be divided into two basic categories: music that is created solely by the animal (or in some cases plant), and music which is based upon animal noises but which is arranged by a human composer. Some forms of music use recorded sounds of nature as part of the music, for example new-age music uses the nature sounds as backgrounds for ...
Unlike much western music, Arabic music includes quarter tones halfway between notes, often through the use of stringed instruments (like the oud) or the human voice. Further distinguishing characteristics of Middle Eastern and North African music include very complex rhythmic structures, generally tense vocal tone, and a monophonic texture .
Microtonal music can also refer to music which uses intervals not found in the Western system of twelve equal intervals to the octave. to Microtonal music also includes music using intervals not found in the customary Western system of twelve equal intervals per octave. I consider this view 'europocentric'.
Prehistoric music (previously called primitive music) is a term in the history of music for all music produced in preliterate cultures , beginning somewhere in very late geological history. Prehistoric music is followed by ancient music in different parts of the world, but still exists in isolated areas.
Since music may facilitate social cohesion, improve group effort, reduce conflict, facilitate perceptual and motor skill development, and improve trans-generational communication, [12] music-like behavior may at some stage have become incorporated into human culture. Another proposed adaptive function is creating intra-group bonding. In this ...
