Tenn. R. Civ. P. 30.03
Examination and cross-examination of witnesses may proceed as permitted at the trial under the Tennessee Rules of Evidence. The officer before whom the deposition is to be taken shall put the witness on oath and shall personally, or by someone acting under the officer's direction and in his presence, record the testimony of the witness. The testimony shall be taken stenographically or recorded by any other means ordered in accordance with Rule 30.02(4). If requested by one of the parties, the testimony shall be transcribed.
All objections made at time of the examination to the qualifications of the officer taking the deposition, or to the manner of taking it, or to the evidence presented, or to the conduct of any party, and any other objection to the proceedings, shall be noted by the officer upon the deposition. Evidence objected to shall be taken subject to the objections. Any objection to evidence during a deposition shall be stated concisely and in a non-argumentative and non-suggestive manner. A deponent may be instructed not to answer only when necessary to preserve a privilege, to enforce a limitation on evidence directed by the court, or to present a motion to terminate or limit examination. In lieu of participating in the oral examination, parties may serve written questions in a sealed envelope on the party taking the deposition and that party shall transmit them to the officer, who shall propound them to the witness and record the answers verbatim.

Advisory Commission Comment [2016].
Rule 30.03 provides that "[e]xamination and cross-examination of witnesses may proceed as permitted at the trial under the Tennessee Rules of Evidence." This language does not imply that Tenn. R. Evid. 615 is applicable to depositions. Unless otherwise ordered by the court, a lawyer may communicate with a deponent about deposition procedure or the substance of deposition testimony before, during (unless a question is pending) or after the deposition; however, such communications are subject to the Rules of Professional Conduct including, but not limited to, Tenn. Sup. Ct. R. 8, RPC 3.3 and RPC 3.4.
