Pure tones have been used by 19th century physicists like Georg Ohm and Hermann von Helmholtz to support theories asserting that the ear functions in a way equivalent to a Fourier frequency analysis. [4] [5] In Ohm's acoustic law, later further elaborated by Helmholtz, musical tones are perceived as a set of pure
In the late 1930s, composer Paul Hindemith ranked musical intervals according to their relative dissonance based on these and similar harmonic relationships. [ 11 ] Below is a comparison between the first 31 harmonics and the intervals of 12-tone equal temperament (12TET), octave displaced and compressed into the span of one octave.
Tracing the y component of a circle while going around the circle results in a sine wave (red). Tracing the x component results in a cosine wave (blue). Both waves are sinusoids of the same frequency but different phases. A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine ...
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 ...
The World in Six Songs: How the Musical Brain Created Human Nature is a popular science book written by the McGill University neuroscientist Daniel J. Levitin, and first published by Dutton Penguin in the U.S. and Canada in 2008, and updated and released in paperback by Plume in 2009, and translated into six languages.
Traditionally in Western music, a musical tone is a steady periodic sound. A musical tone is characterized by its duration , pitch , intensity (or loudness ), and timbre (or quality). [ 1 ] The notes used in music can be more complex than musical tones, as they may include aperiodic aspects, such as attack transients , vibrato , and envelope ...
Ecomusicology considers aspects of environmental sustainability within music production and performance. For example, the relationship between a demand for a certain musical instrument as well as the costs and impacts of its production, has been an area of interest for Ecomusicologists investigating the sustainability of the consumption and production of music or musical instruments.

Musical form is the plan by which a short piece of music is extended. The term "plan" is also used in architecture, to which musical form is often compared. Like the architect, the composer must take into account the function for which the work is intended and the means available, practicing economy and making use of repetition and order. [10]
