Multi-instrumentalists who play closely related instruments, a practice known as doubling are common in orchestra (e.g., flute players who double on piccolo and percussion players, who play snare drum, cymbals, bass drum, etc.), in jazz (e.g., saxophone players who double on clarinet or flute; or double bass players who also play electric bass); in music theatre pit orchestras (e.g., reed players who are required to play numerous reed instruments); and in other areas of classical music (e.g., church piano players are often expected to play the church's pipe organ or Hammond organ as well). Popular music composers and songwriters are often multi-instrumentalists. In pop and rock, it is more common than in classical or jazz for performers to be multi-instrumentalists on instruments that are not from the same family: it is common for pop and rock musicians to play both guitar and keyboards. Many bluegrass musicians are multi-instrumentalists. Some musicians' unions or associations specify a higher rate of pay for musicians who double on two or more instruments for a performance or recording.  - A record producer or music producer oversees and manages the sound recording and production of a band or performer's music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process. The roles of a producer vary. He or she may gather musical ideas for the project, collaborate with the artists to select cover tunes or original songs by the artist/group, work with artists and help them to improve their songs, lyrics or arrangements.   - Albums of recorded music were developed in the early 20th century, first as books of individual 78rpm records, then from 1948 as vinyl LP records played at  rpm. Vinyl LPs are still issued, though in the 21st century album sales have mostly focused on compact disc (CD) and MP3 formats.
