In modern academia, music theory is a subfield of musicology, the wider study of musical cultures and history. Music theory is often concerned with abstract musical aspects such as tuning and tonal systems, scales, consonance and dissonance, and rhythmic relationships. In addition, there is also a body of theory concerning practical aspects ...
A theory of everything ( TOE ), final theory, ultimate theory, unified field theory, or master theory is a hypothetical, singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [ 1]: 6 Finding a theory of everything is one of the major unsolved problems in physics ...
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.
Fundamental frequency. The fundamental frequency, often referred to simply as the fundamental, is defined as the lowest frequency of a periodic waveform. In music, the fundamental is the musical pitch of a note that is perceived as the lowest partial present. In terms of a superposition of sinusoids, the fundamental frequency is the lowest ...
Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
In psychoacoustics, a pure tone is a sound with a sinusoidal waveform; that is, a sine wave of constant frequency, phase-shift, and amplitude. [ 1] By extension, in signal processing a single-frequency tone or pure tone is a purely sinusoidal signal (e.g., a voltage). A pure tone has the property – unique among real-valued wave shapes ...
String theory. In physics, string theory is a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings. String theory describes how these strings propagate through space and interact with each other. On distance scales larger than the string scale, a string looks just ...
Philosophy of music. Philosophy of music is the study of "fundamental questions about the nature and value of music and our experience of it". [1] The philosophical study of music has many connections with philosophical questions in metaphysics and aesthetics. The expression was born in the 19th century and has been used especially as the name ...
