Prepare for the tutorial by becoming acquainted with the student's monologue material. Generally, a monologue tutorial will cover at least two pieces, contrasting in style and tone. If possible, find out the performer's material and obtain a copy. Read over the monologue pieces and decide what is the overall tone of each. Make any notes about the structure or themes of the monologues in preparation for the tutorial.
Begin the tutorial session by having the student perform the monologues exactly as he or she would at an audition, complete with an introduction. Make any necessary notes about the performance, paying careful attention to things such as interpretation, pace, inflection, facial expression and body language. Note-taking while watching a performer can be challenging, and it may be necessary to ask the students to repeat the reading to get all your notes accurately recorded.
Discuss your notes with the student. Do not be overly critical of things such as interpretation. The performer has a right to put his or her own spin on the text of a monologue. However, if you feel that a student is interpreting a monologue incorrectly, ask him why he made the various stylistic choices. Open up a dialogue about the history and structure of the monologues, pointing out any needed adjustments. Do not offer "line readings," where you show the performer how it should be read. Such readings do not offer constructive direction, but rather create a stale mimicry in your student's performance.
After the discussion, suggest several changes for the performer to try and have him read through the monologues again. Watch for the changed areas; likely, very little will change at first. Monologues are rehearsed so many times that the performances often become engrained and stale. Creating periodical small changes in the pace or interpretation of the lines helps to keep things fresh. Have the student repeat the readings as many times as necessary to achieve the suggested changes.
Finally, ask the student to make some new choices concerning the performance. Ask him to switch line inflections, change facial expressions or change the pace, all at his discretion. The result should be a refreshed version of the monologues, taken from a new perspective gained by the student due to your suggestions and notes as an instructor.
