Dress rehearsal
The dress rehearsal is a full-scale rehearsal where the actors and/or musicians perform every detail of the performance. For a theatrical performance, cast members wear their costumes. The actors may use props and backdrops and do not use scripts although the stage manager and director might do so.
For a musical performance, the dress rehearsal does not require wearing formal concert outfits (such as, tuxedos and gowns). In music, the dress rehearsal is the final rehearsal before the performance;
initial rehearsals will often involve working on challenging sections of the piece or pieces, but during the dress rehearsal, the piece or pieces are typically played in their entirety.
Theatre or opera house
In theatre, a performing arts ensemble rehearses a work in preparation for performance before an audience. Rehearsals that occur early in the production process are sometimes referred to as "run-throughs." Typically, a run-through does not involve most of the technical aspects of a performance, such as costumes, lights, and sound and is primarily used to assist performers in learning dialogue or music and to solidify aspects of
blocking, choreography, and stage movement.
A "cue to cue" or "Q-2-Q" is a type of

.
Q-2-Qs are often preceded by a "dry tech" in which the technicians rehearse their technical cues (such as turning on stage lights or triggering sound effects or recorded music) without the actual performers being present at the rehearsal. A "dress rehearsal" is a rehearsal or series of rehearsals in which the ensemble dresses in costume, as they will dress at the performance for the audience. The entire performance will be run from beginning to end, exactly as the real performances will be, including pauses for intermissions. An "open dress" is a dress rehearsal to which specific individuals have been invited to attend as audience members.
They may include patrons (who pay a reduced ticket price), family and friends of the ensemble, or reviewers from the media. The dress rehearsal is often the last set of rehearsals before the concert performance and falls at the end of technical week. A "preview", although technically a performance as there is a full audience, including individuals who have paid for admission, is arguably also a rehearsal in as far as it is common in complex performances for the production to stop or even to return to an earlier point in the performance if there are unavoidable or unresolvable problems. Audience members typically pay a lower price to attend a preview performance.

) rehearses a piece (or song) in order to coordinate the rhythmic ensemble, ensure that the
intonation of pitches of the different sections matches exactly, and coordinate the
dynamics (changes in loudness and softness) and
phrasing. A professional ensemble will typically only rehearse an orchestral work for two or three rehearsals which are held several days before the first performance. A professional ensemble is much less likely than an amateur orchestra to play the piece all the way through in the first rehearsals. Instead, a professional ensemble will typically review passages which pose challenges from the point of view of rhythmic or harmonic coordination. An example of a passage that might pose rhythmic coordination challenges would be a contemporary work which involves

s to direct the orchestra to them. While classical conductors do not typically speak to direct the orchestra during concerts, during rehearsals, the conductor speaks to communicate their artistic vision for the piece and explain the "articulation" (note lengths), tone colors, and tempos they would like to use. During initial rehearsals, the conductor frequently stops the rehearsal to ask players or sections to change the way they are playing or provide guidance to the orchestra. For a choir, the choral conductor will lead rehearsals. In cases where a choir is preparing a piece which will be sung with an orchestra, the initial rehearsals may be led by the choir's conductor and the rehearsals closer to the concert by the orchestra's conductor.
For works that present a particular challenge for certain sections (e.g., a complex, exposed passage for the violas), orchestras may have sectional rehearsals or sectionals in which a section rehearses on their own under the direction of the principal player or, in some cases, also with the conductor (e.g., in the case of a very rhythmically challenging piece).

may be used to sound out the tempo prior to the commencement of a piece. For musical performances, a dress rehearsal does not imply dressing in concert dress. It is a final rehearsal before performance where generally the ensemble will run through the program as if there were an audience. In some orchestras, there may be a limited audience during the dress rehearsal (typically university music students or other invited guests).
Amateur classical ensembles
Amateur orchestras or chamber ensembles, such as university or community groups, rehearse music for a number of reasons. While an amateur ensemble does rehearsals for many of the same reasons as a professional ensemble—to coordinate the rhythmic ensemble and intonation—with an amateur group the conductor has to do much more teaching to the orchestra. However, amateur musicians are much more likely to make note mistakes, transposition errors or play with incorrect intonation or rhythms; the conductor must point these issues out to the performers and give them advice on how to correct them. In amateur groups, players may not have strong ensemble skills, so the conductor may have to coach players about how to learn to blend their sound well with other sections or how to coordinate rhythmic passages that are played by different sections, or how to mark their part after they make an error to prevent the error from being repeated.
Rehearsals are also used to teach ensemble members about

, so that they can learn the different playing styles and tones used in music from different eras. As well, orchestra conductors select pieces so that players can learn new skills, such as more complicated rhythms. For an amateur ensemble, the rehearsals are used to give the players an opportunity to have repeated chances to learn to perform difficult passages in an ensemble context. Amateur choirs use rehearsals to build choral singing skills, such as singing with a good ensemble and with solid intonation and vocal tone. Amateur groups are much more likely than professional groups to hold sectional rehearsals. Another difference between rehearsals in an amateur orchestra and a professional orchestra is the number of rehearsals. A community orchestra or university ensemble may have ten or even fifteen rehearsals over several months to prepare a major symphony; a professional orchestra might prepare that same symphony in two rehearsals over two days.
In an amateur performance consisting of miscellaneous items, such as songs, theatrical performances, skits, and musical pieces, it is common to have "a walk through rehearsal" on the concert day. This "walk through" requires the musicians, singers and actors to walk on and off stage without actually performing their full pieces. Each soloist or ensemble has had a number of previous rehearsals to work on their specific song or piece. The "walk through" helps performers to remember which performers need to go on stage together (e.g., a jazz singer needs to go onstage with her piano accompanist and bass player), what materials or items are required (e.g., a string quartet will require four chairs and four music stands, in addition to their instruments), and which lighting or

bands rehearse before performances. Rehearsals assemble the elements of a musical event, offering an experimental space where sounds and rhythms are put together and taken apart, played with, argued over, and refined. In these styles of music, rehearsals may be less formal than in a classical orchestra context. However, the purpose of rehearsals is the same: to ensure that all the band members can play and/or sing their parts with a good rhythmic ensemble, correct intonation, and the right "feel" and style. As with classical rehearsals, the earlier rehearsals for a show often focus more on working out the most difficult sections of songs, such as transitions from one tempo to another tempo, modulations to a new key, or coordinating a duet between two solo instruments. The rehearsals closer to the performance are more likely to involve run-throughs of entire songs. Whereas Classical rehearsals are led by the conductor or choir leader, popular music band rehearsals are typically led by the

The use of rehearsals and dress rehearsals extends beyond the performing arts. When an organization has to learn how to implement a new process, it may rehearse the activity beforehand. Emergency-planning organizations often rehearse their preparations for responding to
civil disasters; in some cases, there may even be actors playing the role of "injured people", so that emergency workers can learn how to provide assistance. Armies that are planning an attack on a certain target may create a mock-up of the target and rehearse the attack. The
