Part may refer to:
A system is a set of interacting or interdependent component parts forming a complex/intricate whole. Every system is delineated by its spatial and temporal boundaries, surrounded and influenced by its environment, described by its structure and purpose and expressed in its functioning.
The term system may also refer to a set of rules that governs structure and/or behavior. Alternatively, and usually in the context of complex social systems, the term is used to describe the set of rules that govern structure and/or behavior.
The term "system" comes from the Latin word systēma, in turn from Greek σύστημα systēma: "whole compounded of several parts or members, system", literary "composition".
According to Marshall McLuhan,
"System" means "something to look at". You must have a very high visual gradient to have systematization. In philosophy, before Descartes, there was no "system". Plato had no "system". Aristotle had no "system".
In the 19th century the French physicist Nicolas Léonard Sadi Carnot, who studied thermodynamics, pioneered the development of the concept of a "system" in the natural sciences. In 1824 he studied the system which he called the working substance (typically a body of water vapor) in steam engines, in regards to the system's ability to do work when heat is applied to it. The working substance could be put in contact with either a boiler, a cold reservoir (a stream of cold water), or a piston (to which the working body could do work by pushing on it). In 1850, the German physicist Rudolf Clausius generalized this picture to include the concept of the surroundings and began to use the term "working body" when referring to the system.
A part (or voice) is a strand or melody of music played by an individual instrument or voice (or group of identical instruments or voices) within a larger work. Parts may be referred to as an outer part (the top and bottom parts) or an inner part (those in between). Part-writing (or voice leading) is the composition of parts in consideration of harmony and counterpoint. In the context of polyphonic composition the term voice may be used instead of part to denote a single melodic line or textural layer. The term is generic, and is not meant to imply that the line should necessarily be vocal in character, instead referring to instrumentation or simply to register.
Allen Forte defines a voice thus:
Codex Calixtinus (12th century) contains the earliest extant decipherable part music.
In music notation, a part also refers to the separate printed or manuscript copies of the music for each individual instrumental performer in an ensemble or orchestra, as distinct from the score, which shows the music for all the instruments and/or voices.
part-time love
I need somebody who's consistent
With me
Someone already there when i need
Company
'cause when l'm feeling low
I don't want to have to go out
Looking
For a part-time kind of love
And when the dreams and rainbows
Start to disappear
Don't want somebody up and running
Out here
'cause when you stop and start
Baby it's just too hard upon
My heart
That part-time kind of love
And i can't take you darling living here
Wait and see
I want somebody who's committed
Now to me
Somewhere, someday you'll have
To take a chance
So if you like the music baby
Get up and dance
And if we grow together daring to dream
I know we'll find our shares of
Peaches and cream
And when the juices flow
I don't want no no no excuses
Just want your full time love
For me
Just want your full time love
