Regardless of the setting, musicians, singers, and related workers spend considerable time practicing, alone and with their band, orchestra, or other musical group. Musicians often specialize in a particular kind of music or performance. Instrumental musicians, for example, play a musical instrument in an orchestra, band, rock group, or jazz group. Some play a variety of string, brass, woodwind, or percussion instruments or electronic synthesizers. Those who learn several related instruments, such as the flute and clarinet, have better employment opportunities.
Singers interpret music using their knowledge of voice production, melody, and harmony.
They sing character parts or perform in their own individual style. Singers are often classified according to their voice range soprano, contralto, tenor, baritone, or bass or by the type of music they sing, such as opera, rock, reggae, folk, rap, or country and western. Composers create original music such as symphonies, operas, sonatas, or popular songs. They transcribe ideas into musical notation using harmony, rhythm, melody, and tonal structure. Although most songwriters still practice their craft on instruments or with pen and paper, many songwriters now compose and edit music using computers.
