MUZIK

Music is an art form whose medium is sound. Common elements of music are pitch (which governs melody and harmony), rythm (and its associated concepts tempo, meter, and artculation), dynamics, and the sonic qualities of timbre and texture.

The music that composers make can be heard through several media the most traditional way is to hear it live, in the presence, or as one of the musicians. Live music can also be broadcast over the radio,television or the Internet. Some musical styles focus on producing a sound for a performance, while others focus on producing a recording that mixes together sounds that were never played "live." Recording, even of essentially live styles, often uses the ability to edit and splice to produce recordings considered better than the actual performance.

As talking pictures emerged in the early 20th century, with their prerecorded musical tracks, an increasing number of movie house orchestra musicians found themselves out of work. During the 1920s live musical performances by orchestras,pianists, and theater organists were common at first-run theaters. With the coming of the talking motion pictures, those featured performances were largely eliminated. The American Federation of Musicians(AFM) took out newspaper advertisements protesting the replacement of live musicians with mechanical playing devices. One 1929 ad that appeared in the pittsberg press.

Since legislation introduced to help protect performers, composers, publishers and producers, including the Audio Home recording Act of 1992 in the United States, and the 1979 recordings and live performances have also become more accessible through computers, devices and Internet in a form that is commonly known as Music on demand.

In many cultures, there is less distinction between performing and listening to music, since virtually everyone is involved in some sort of musical activity, often communal. In industrialized countries, listening to music through a recorded form, such as sound recording or watching a music video, became more common than experiencing live performance, roughly in the middle of the 20th century.

Sometimes, live performances incorporate prerecorded sounds. For example, a disc jockey uses disc records for scratching, and some 20th century works have a solo for an instrument or voice that is performed along with music that is prerecorded onto a tape. Computers and many keyboards can be programmed to produce and play Musical  Instrumental Digital Interface (MIDI) music. Audiences can also become performers by participating in karaoke, an activity of Japanese origin centered on a device that plays voice-eliminated versions of well-known songs. Most karaoke machines also have video screens that show lyrics to songs being performed; performers can follow the lyrics as they sing over the instrumental tracks.
