Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
A scintillation detector or scintillation counter is obtained when a scintillator is coupled to an electronic light sensor such as a photomultiplier tube (PMT), photodiode, or silicon photomultiplier. PMTs absorb the light emitted by the scintillator and re-emit it in the form of electrons via the photoelectric effect. The subsequent ...
Scintillation is an example of luminescence, whereby light of a characteristic spectrum is emitted following the absorption of radiation. The scintillation process can be summarized in three main stages: conversion, transport and energy transfer to the luminescence center, and luminescence.
The scintillator consists of a transparent crystal, usually a phosphor, plastic (usually containing anthracene) or organic liquid (see liquid scintillation counting) that fluoresces when struck by ionizing radiation. Cesium iodide (CsI) in crystalline form is used as the scintillator for the detection of protons and alpha particles.
The use of found objects in modern classical music is often connected to experiments in indeterminacy and aleatoric music by such composers as John Cage and Karlheinz Stockhausen. However, it has reached its ascendancy in those areas of popular music as well, such as the ambient works of Brian Eno. In Eno's influential work, found objects are ...
Silver, added to zinc sulfide to produce a phosphor/scintillator used in radium dials, spinthariscopes, and as a common blue phosphor in color CRTs, and to zinc sulfide-cadmium sulfide used as a phosphor in black-and-white CRTs (where the ZnS/(Zn,Cd)S ratio determines the blue/yellow balance of the resulting white); short afterglow
In discussing three-note slides, Türk states that the character of the slide is wholly dependent on the mood of the music: a lively work will suggest a fast slide, and a "sorrowful" work will be the appropriate place for a slower decoration. [11] He states that the three-note slide is used primarily on the strong beat.
"b–a–c–h is beginning and end of all music" (Max Reger 1912) In music, the BACH motif is the motif, a succession of notes important or characteristic to a piece, B flat, A, C, B natural. In German musical nomenclature, in which the note B natural is named H and the B flat named B, it forms Johann Sebastian Bach's family name.
