Percussion notation is a type of musical notation indicating notes to be played by percussion instruments. As with other forms of musical notation, sounds are represented by symbols which are usually written onto a musical staff (or stave). Percussion instruments are generally grouped into two categories: pitched and non-pitched. The notation ...
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook ( colloq. lab notebook or lab book ) is a primary record of research . Researchers use a lab notebook to document their hypotheses , experiments and initial analysis or interpretation of these experiments.
See list of percussion instruments by type for some shorter, more focused lists. Use the sorting arrows on the common usage column to group instruments as pitched, unpitched or both. Use the sorting arrows on the Classification column to group instruments according to their Hornbostel–Sachs classification.
The center of percussion is often discussed in the context of a bat, racquet, door, sword or other extended object held at one end. The same point is called the center of oscillation for the object suspended from the pivot as a pendulum , meaning that a simple pendulum with all its mass concentrated at that point will have the same period of ...
Percussion notation conventions are varied because of the wide range of percussion instruments. Percussion instruments are generally grouped into two categories: pitched (e.g. glockenspiel or tubular bells) and non-pitched (e.g. bass drum and snare drum). The notation of non-pitched percussion instruments is less standardized.
Historically, the definition of a scientific instrument has varied, based on usage, laws, and historical time period. [1] [2] [3] Before the mid-nineteenth century such tools were referred to as "natural philosophical" or "philosophical" apparatus and instruments, and older tools from antiquity to the Middle Ages (such as the astrolabe and pendulum clock) defy a more modern definition of "a ...
Found objects are sometimes used in music, often to add unusual percussive elements to a work. Their use in such contexts is as old as music itself, as the original invention of musical instruments almost certainly developed from the sounds of natural objects rather than from any specifically designed instruments.

The earliest mention of the jal tarang is found in Vatsyayana's Kamasutra, as playing on musical glasses filled with water. [1] Jal tarang was also mentioned in the medieval Sangeet Parijaat text, which categorized the instrument under Ghan-Vadya (idiophonic instruments in which sound is produced by striking a surface, also called concussion idiophones.)
