Musical notationMusic notation or musical notation is any system used to visually represent aurally perceived music played with instruments or sung by the human voice through the use of written, printed, or otherwise-produced symbols, including notation for durations of absence of sound such as rests. The types and methods of notation have varied between cultures and throughout history, and much information about ancient music notation is fragmentary.
OrchestraAn orchestra (ˈɔːrkɪstrə; ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: bowed string instruments, such as the violin, viola, cello, and double bass woodwinds, such as the flute, oboe, clarinet, and bassoon brass instruments, such as the horn, trumpet, trombone, cornet, and tuba percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, and mallet percussion instruments Other instruments such as the piano, harpsichord, and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments, and guitars.
