指揮: conducting music and commanding rescue training
Compare 指揮 for a director leading a performance from the side of a stage with training under a captain's command. Identify the leader, directed activity, and participants without adding a real rescue or extra performance roles.
The person conducting and the stated location
指揮 (しき) appears with leading or directing an activity. 「監督が舞台の袖から演奏を指揮した。」 means “The director conducted the performance from the side of the stage.” The director conducted the performance from the side of the stage. Identify the director as the person conducting and the performance as the activity being led.
Conducting the performance does not state that the director also played an instrument or acted onstage. 舞台の袖から identifies the location in this example. The side of a stage should not become a required location for every act of conducting.
Training under a captain's command
「隊長の指揮のもとで救助訓練を行った。」 means “We conducted rescue training under the captain's command.” The captain supplies the command, while the activity carried out is rescue training. 指揮のもとで expresses that the activity took place under the captain's direction.
Rescue training is an exercise, so it should not be retold as a completed rescue at an actual emergency. Being under the captain's command also does not establish that the captain performed every action alone. Keep the leadership role separate from carrying out the training.
One leadership term with different activities
The first 指揮 example concerns a musical performance, while the second concerns rescue training. The term is not limited to music in these examples. Identifying what is being led reveals the different activities without changing the leader's role.
監督が演奏を指揮した states the director's conducting action directly; 隊長の指揮のもとで places an activity under the captain's command. Neither sentence assigns additional roles as instrumentalist, actor, or sole rescuer. Preserve the leader, the activity, and the relationship in which it was carried out.
Does 指揮 in 「隊長の指揮のもとで救助訓練を行った。」 refer only to a musical performance?
Show the answer and why
No. Here it refers to the captain's command under which rescue training was carried out. The directed activity differs from the director's musical performance. The sentence does not describe a completed real rescue or say that the captain did everything alone.
