Information: - Music is an art form and cultural activity whose medium is sound and silence, which exist in time. The common elements of music are pitch (which governs melody and harmony), rhythm (and its associated concepts tempo, meter, and articulation), dynamics (loudness and softness), and the sonic qualities of timbre and texture (which are sometimes termed the "color" of a musical sound). Different styles or types of music may emphasize, de-emphasize or omit some of these elements. Music is performed with a vast range of instruments and vocal techniques ranging from singing to rapping; there are solely instrumental pieces, solely vocal pieces (such as songs without instrumental accompaniment) and pieces that combine singing and instruments. The word derives from Greek ("mousike"; "art of the Muses"). In its most general form, the activities describing music as an art form include the production of works of music (songs, tunes, symphonies, and so on), the criticism of music, the study of the history of music, and the aesthetic examination of music. Ancient Greek and Indian philosophers defined music as tones ordered horizontally as melodies and vertically as harmonies. Common sayings such as "the harmony of the spheres" and "it is music to my ears" point to the notion that music is often ordered and pleasant to listen to. However, 20th-century composer John Cage thought that any sound can be music, saying, for example, "There is no noise, only sound." - The Symphony No. 4 in A major , Op. 90 , commonly known as the Italian , is an orchestral symphony written by German composer Felix Mendelssohn . The work has its origins ( such as the composer 's '' Scottish / 3rd Symphony '' and '' The Hebrides '' overture ) in the tour of Europe which occupied Mendelssohn from 1829 to 1831 . Its inspiration is the colour and atmosphere of Italy , where Mendelssohn made sketches but left the work incomplete : This is Italy ! And now has begun what I have always thought ... to be the supreme joy in life . And I am loving it . Today was so rich that now , in the evening , I must collect myself a little , and so I am writing to you to thank you , dear parents , for having given me all this happiness . In February he wrote from Rome to his sister Fanny , The Italian symphony is making great progress . It will be the jolliest piece I have ever done , especially the last movement . I have not found anything for the slow movement yet , and I think that I will save that for Naples . The Italian Symphony was finished in Berlin on 13 March 1833 , in response to an invitation for a symphony from the London ( now Royal ) Philharmonic Society ; he conducted the first performance himself in London on 13 May 1833 at a London Philharmonic Society concert . The symphony 's success , and Mendelssohn 's popularity , influenced the course of British music for the rest of the century . The Germania Musical Society of Boston gave the first performance in the United States , on 1 November 1851 , with Carl Bergmann conducting . Mendelssohn himself , however , remained unsatisfied with the composition , which cost him , he said , some of the bitterest moments of his career ; he revised it in 1834 and even planned to write alternate versions of the second , third , and fourth movements . He never published the symphony , and it appeared in print only in 1851 ; thus it is numbered as his ' Symphony No. 4 ' , even though it was in fact the third he composed . The piece is scored for 2 flutes , 2 oboes... - A composer (Latin "compn"; literally "one who puts together") is a person who creates or writes music, which can be vocal music (for a singer or choir), instrumental music (e.g., for solo piano, string quartet, wind quintet or orchestra) or music which combines both instruments and voices (e.g., opera or art song, which is a singer accompanied by a pianist). The core meaning of the term refers to individuals who have contributed to the tradition of Western classical music through creation of works expressed in written musical notation (e.g., sheet music scores). - Jakob Ludwig Felix Mendelssohn Bartholdy (3 February 1809 ), born and widely known as Felix Mendelssohn, was a German composer, pianist, organist and conductor of the early Romantic period.

Information: - Game Jackal is a PC application developed by Antiguan - based company SlySoft that allows users to play PC game titles without the need for the game 's media to be in the CD - ROM or DVD - ROM drive . The program functions similar to a virtual drive ; however , instead of making use of large disc images , Game Jackal uses a proprietary format which takes up considerable less storage space by working to only capture data the game requires to run . Game Jackal is advertised to work with around 90 % of games on the market , including games such as Sid Meier 's Railroads ! , Neverwinter Nights 2 and Need For Speed Carbon . While the authors admit not every title is bound to work with Game Jackal , support is gradually improving and regular updates which combat various bugs and blacklisting , as well as expanded functionality in the building of its profiles . Game Jackal works by establishing a game profile which is used to store all of the game 's relevant data . To begin , an original copy of the game is needed to allow Game Jackal to successfully ' capture ' the game for use later . If a first attempt at capturing a profile does not succeed , it may be performed again : anything else Game Jackal picks up will simply be added to the profile . - Read-only memory (ROM) is a type of non-volatile memory used in computers and other electronic devices. Data stored in ROM can only be modified slowly, with difficulty, or not at all, so it is mainly used to store firmware (software that is closely tied to specific hardware and unlikely to need frequent updates) or application software in plug-in cartridges. - A CD-ROM is a pre-pressed optical compact disc which contains data. The name is an acronym which stands for "Compact Disc Read-Only Memory". Computers can read CD-ROMs, but cannot write to CD-ROMs which are not writable or erasable. - Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony. The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM). Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD. Audio CD players have been commercially available since October 1982, when the first commercially available CD player was released in Japan. - An acronym is a word or name formed as an abbreviation from the initial components in a phrase or a word, usually individual letters (as in "NATO" or "laser") and sometimes syllables (as in "Benelux"). - CD-R (Compact Disc-Recordable) is a digital optical disc storage format. A CD-R disc is a compact disc that can be written once and read arbitrarily many times. Given the information, choose the subject and object entities that have the relation of 'instance of'.
