Some even have a musical keyboard linked to a computer which compiles the digital information into musical notation while they play. Also, they may program the composition in musical notation into the computer, which can play back the piece. Arrangers transcribe and adapt musical composition to a particular style for orchestras, bands, choral groups, or individuals. Orchestra conductors lead instrumental music groups, such as orchestras, dance bands, and various popular ensembles. Conductors audition and select musicians, choose the music to accommodate the talents and abilities of the musicians, and direct rehearsals and performances, applying conducting techniques to achieve desired musical effects.
Choral directors lead choirs and glee clubs, sometimes working with a band or orchestra conductor.
Directors audition and select singers and direct them at rehearsals and performances to achieve harmony, rhythm, tempo, shading, and other desired musical effects. All musicians spend a considerable amount of time practicing, individually and with their band, orchestra, or other musical group. Working Conditions Musicians often perform at night and on weekends and spend considerable time in practice and rehearsal. Performances frequently require travel. Because many musicians find only part-time work or experience unemployment between engagements, they often supplement their income with other types of jobs.
