Session musician

Session musicians may play in a wide range of genres or specialize in a specific genre (e.g., country music or jazz). Some session musicians with a classical music background may focus on film score recordings. Even within a specific genre specialization, there may be even more focused sub-specializations. For example, a sub-specialization within trumpet session players is "high note specialist."

The working schedule for session musicians often depends on the terms set out by musicians' unions or associations, as these organizations typically set out rules on performance schedules (e.g., regarding the length of sessions and breaks). The length of employment may be as short as a single day, in the case of recording a brief demo song, or as long as several weeks if an album or film score is being recorded.

Musicians' associations and unions often set out the remuneration terms. Some musicians may get the minimum scale rate set out by the union. Heavily in-demand session musicians may earn much more. The union rates may vary based on whether it is a music recording versus a film/television recording. While the film/television rates may be lower, there may also be residual payments to compensate them for reruns, DVD sales, streaming usage, and so on.

Session musicians often have to bring their own instruments, such as in the case of guitar, bass, woodwinds, and brass. It is expected that studio musicians will have well-maintained professional-tier instruments. In some cases, larger or heavier instruments may be provided by the recording studio, such as a grand piano or Hammond organ and Leslie speaker. In certain cases, a session musicians may bring some instruments or musical gear and use them with larger instruments that are provided by the studio, such as a synthesizer player, who might bring rack-mounted synth modules and connect them to the studio's MIDI controller stage piano. Similarly, if the studio has a selection of well-known bass amplifiers, and speaker cabinets, a bass player may only have to bring basses and effect units.

The requirement to read different types of music notation, improvise and/or "play by ear" varies according to the type of recording session and the genres of music being performed. Classical musicians and many jazz and popular music musicians are expected to read music notation and do sight-reading. In jazz, rock, and many popular music genres, performers may be expected to read chord charts and improvise accompaniment and solos. In country music, performers may be expected to read Nashville Number System charts and improvise accompaniment and solos. In many traditional and folk music styles, performers are expected to be able to play by ear.

Session musicians need a nuanced sense of the playing styles and idioms used in different genres. For example, a sax player who mainly plays jazz needs to know the R&B style if they are asked to improvise a solo in an R&B song. Similarly, a bass player asked to improvise a walking bassline in a rockabilly song needs to know the stock lines and cliches used in this genre.

Regardless of the styles of music session musicians play, some qualities are universal: punctuality in arriving at the session; rhythmic and intonation precision; ability to play with good ensemble and excellent blending with the other performers; willingness to take direction from bandleaders, music directors, and music producers; and having good musical taste in regards to choices with musical ornaments and musical phrasing.

During the 1950s and 1960s, session players were usually active in local recording scenes concentrated in places such as Los Angeles, New York City, Nashville, Memphis, Detroit, and Muscle Shoals.^[4][5][6] Each local scene had its circle of "A-list" session musicians, such as The Nashville A-Team that played on numerous country and rock hits of the era, the two groups of musicians in Memphis, both the Memphis Boys and the musicians who backed Stax/Volt recordings, and the Funk Brothers in Detroit, who played on many Motown recordings.^[5]

At the time, multi-tracking equipment, though common, was less elaborate, and instrumental backing tracks were often recorded "hot" with an ensemble playing live in the studio.^[7] Musicians had to be available "on call" when producers needed a part to fill a last-minute time slot.^[8] In the 1960s, Los Angeles was considered the top recording destination in the United States — consequently studios were constantly booked around the clock, and session time was highly sought after and expensive.^[9] Songs had to be recorded quickly in the fewest possible takes.^[10] In this environment, Los Angeles producers and record executives had little patience for needless expense or wasted time and depended on the service of reliable standby musicians who could be counted on to record in a variety of styles with minimal practice or takes, and deliver hits on short order.^[8][11]

A studio band is a musical ensemble that is in the employ of a recording studio for the purpose of accompanying recording artists who are customers of the studio. The use of studio bands was more common during the 1960s with groups such Booker T. & the M.G.'s. The benefit of having a regular group, an approach which typified Southern soul, is that the group has much more experience playing together, which enables them to get a better sense of ensemble.
