The phrase "technical run" can have several synonyms that convey a similar meaning. For instance, the term "dress rehearsal" is often used to describe a performance or practice session where all technical aspects are tested and potentially adjusted. Alternatively, "tech run" or "technical rehearsal" can be used to describe the same process. Another synonym is "tech check," which is a more focused and faster version of the technical rehearsal, where only the essential aspects of the performance are tested. Last but not least, "dry run" is another synonym that is commonly used in situations where the rehearsal is a simulation of the actual performance.
