The opposition between consonance and dissonance can be made in different contexts: In acoustics or psychophysiology, the distinction may be objective.In modern times, it usually is based on the perception of harmonic partials of the sounds considered, to such an extent that the distinction really holds only in the case of harmonic sounds (i.e. sounds with harmonic partials).
Resonances can also be thought of as unstable particles, with the formula in the Universal resonance curve section of this article applying if Γ is the particle's decay rate and Ω is the particle's mass M. In that case, the formula comes from the particle's propagator, with its mass replaced by the complex number M + iΓ.
Dissonance has several meanings related to conflict or incongruity: . Cognitive dissonance is a state of mental conflict.; Cultural dissonance is an uncomfortable sense experienced by people in the midst of change in their cultural environment.
Resolution has a strong basis in tonal music, since atonal music generally contains a more constant level of dissonance and lacks a tonal center to which to resolve.. The concept of "resolution", and the degree to which resolution is "expected", is contextual as to culture and historical period.
Experiment using two tuning forks oscillating at the same frequency.One of the forks is being hit with a rubberized mallet. Although the first tuning fork hasn't been hit, the other fork is visibly excited due to the oscillation caused by the periodic change in the pressure and density of the air by hitting the other fork, creating an acoustic resonance between the forks.
The non-linearity providing the coupling is due to general relativity; accretion disks in Newtonian gravity, e.g. Saturn's rings do not have this particular kind of resonant interaction (they do demonstrate many other kinds of resonances, however). During spacecraft atmospheric entry, the high speed of the spacecraft heats air to a red-hot ...
Post-tonal music theory is the set of theories put forward to describe music written outside of, or 'after', the tonal system of the common practice period.It revolves around the idea of 'emancipating dissonance', that is, freeing the structure of music from the familiar harmonic patterns that are derived from natural overtones.
In particle physics, a resonance is the peak located around a certain energy found in differential cross sections of scattering experiments.These peaks are associated with subatomic particles, which include a variety of bosons, quarks and hadrons (such as nucleons, delta baryons or upsilon mesons) and their excitations.
