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.
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. Arrangers transcribe and adapt musical composition to a particular style for orchestras, bands, choral groups, or individuals. While some arrangers write directly into a musical composition, others use computer software to make changes. Conductors lead instrumental music groups, such as orchestras, dance bands, and various popular ensembles.
