Artist
An artist is a person engaged in an activity related to creating art, practicing the arts, or demonstrating an art. The common usage in both everyday speech and academic discourse is a practitioner in the visual arts only. The term is often used in the entertainment business, especially in a business context, for musicians and other performers (less often for actors). "Artiste" (the French for artist) is a variant used in English only in this context. Use of the term to describe writers, for example, is valid, but less common, and mostly restricted to contexts like criticism.
Diploma
A diploma is a certificate or deed issued by an educational institution, such as college or university, that testifies that the recipient has successfully completed a particular course of study. The word diploma also refers to an academic award which is given after the completion of study in different courses such as diploma in higher education, diploma in graduation or diploma in post graduation etc. Historically, it can also refer to a charter or official document, thus diplomatic, diplomat and diplomacy via the Codex Juris Gentium Diplomaticus.
Instrumental
An instrumental is a musical composition or recording without lyrics, or singing, although it might include some inarticulate vocals, such as shouted backup vocals in a Big Band setting. The word "song" is widely misused by people in the popular music industry to describe any musical composition, whether sung or played only by instruments."The music is primarily or exclusively produced by musical instruments. An instrumental can exist in music notation, after it is written by a composer; in the mind of the composer (especially in cases where the composer himself will perform the piece, as in the case of a blues solo guitarist or a folk music fiddle player); as a piece that is performed live by a single instrumentalist or a musical ensemble, which could range in size from a duo or trio to a large Big Band, concert band or orchestra.
Performance
Performance is completion of a task with application of knowledge, skills and abilities. In work place, performance or job performance means good ranking with the hypothesized conception of requirements of a task role, whereas citizenship performance means a set of individual activity/contribution (prosocial organizational behavior) that supports the organizational culture. In the performing arts, a performance generally comprises an event in which a performer or group of performers present one or more works of art to an audience. Usually the performers participate in rehearsals beforehand. An effective performance is determined by competency of the performer - level of skill and knowledge. Spencer and McClelland in 1994 defined competency as "a combination of motives, traits, self-concepts, attitudes, cognitive behavior skills (content knowledge)" that helps a performer to differentiate themselves superior from average performers. A performance may also describe the way in which an actor performs. In a solo capacity, it may also refer to a mime artist, comedian, conjurer, or other entertainer.
Artist
A writer — and, I believe, generally all persons — must think that whatever happens to him or her is a resource. All things have been given to us for a purpose, and an artist must feel this more intensely. All that happens to us, including our humiliations, our misfortunes, our embarrassments, all is given to us as raw material, as clay, so that we may shape our art.

Performance
"Performance has remained the ideal locus of rock authenticity long after it has ceased to be the real origin of rock music."

Mathematics is too arduous and uninviting a field to appeal to those to whom it does not give great rewards. These rewards are of exactly the same character as those of the artist. To see a difficult uncompromising material take living shape and meaning is to be Pygmalion, whether the material is stone or hard, stonelike logic. To see meaning and understanding come where there has been no meaning and no understanding is to share the work of a demiurge. No amount of technical correctness and no amount of labour can replace this creative moment, whether in the life of a mathematician or of a painter or musician. Bound up with it is a judgement of values, quite parallel to the judgement of values that belongs to the painter or the musician. Neither the artist nor the mathematician may be able to tell you what constitutes the difference between a significant piece of work and an inflated trifle; but if he is not able to recognise this in his own heart, he is no artist and no mathematician.
