Music, is a form of art and entertainment or other human activity that involves organized and audible sounds and silence. It is expressed in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture). Music also involves complex generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, or ceremonial purposes. The definition of what constitutes music varies according to culture and social context. Musical instrument, is a device constructed or modified for the purpose of making music. In principle, anything that produces sound can serve as a musical instrument. The term "musical instrument", however, is generally reserved for items that have a specific musical purpose such as a piano. The academic study of musical instruments is called organology. Organology, is the science of musical instruments and their classification [1]. It embraces study of instruments' history, instruments used in different cultures, technical aspects of how instruments produce sound, and musical instrument classification. There is a degree of overlap between organology, acoustics, ethnomusicology, and musicology. Rock music is a genre of popular music with a prominent vocal melody, accompanied by electric guitar, bass guitar, and drums. Many styles of rock music also use keyboard instruments such as organ, piano, mellotron, and synthesizers. Other instruments sometimes utilized in rock include saxophone, harmonica, violin, flute, French horn, banjo, melodica, and timpani. Also, less common stringed instruments such as mandolin and sitar are used. Rock music usually has a strong back beat, and often revolves around the guitar, either solid electric, hollow electric, or acoustic. Rock music has its roots in 1940s and 1950s rock and roll and rockabilly, which evolved from blues, country music and other influences. According to Allmusic, "In its purest form, Rock & Roll has three chords, a strong, insistent back beat, and a catchy melody. Early rock & roll drew from a variety of sources, primarily blues, R&B, and country, but also gospel, traditional pop, jazz, and folk. All of these influences combined in a simple, blues-based song structure that was fast, danceable, and catchy."[1] In the late 1960s, rock music was blended with folk music to create folk rock, blues to create blues-rock and with jazz, to create jazz-rock fusion, and without a time signature to create psychedelic rock. In the 1970s, rock incorporated influences from soul, funk, and latin music. Also in the 1970s, rock developed a number of subgenres, such as soft rock, heavy metal, hard rock, progressive rock, and punk rock. Rock subgenres that emerged in the 1980s included New Wave, hardcore punk and alternative rock. In the 1990s, rock subgenres included grunge, Britpop, indie rock, and nu metal. A group of musicians specializing in rock music is called a rock band or rock group. Many rock groups consist of a guitarist, lead singer, bass guitarist, and a drummer, forming a quartet. Some groups omit one or more of these roles and/or utilize a lead singer who plays an instrument while singing, sometimes forming a trio or duo; others include additional musicians such as one or two rhythm guitarists and/or a keyboardist. More rarely, groups also utilize stringed instruments such as violins or cellos, and/or horns like saxophones, trumpets or trombones.
