Scholars like Lehman are exulting in “The Last Jedi” because the score is full of such echt-leitmotivic moments. Williams manipulates his library of themes with extreme dexterity, often touching on a familiar motif for just a couple of bars. (Spoilers loom ahead.) In early scenes set at a remote, ruined Jedi temple, we keep hearing an attenuated, beclouded version of the Force motto: this evokes Luke’s embittered renunciation of the Jedi project.
