0:00-0:27 incidental, low brass and strings in tenths
0:27-0:49 incidental music, some of which reminds me of that heard right before Han's death in The Force Awakens
0:49-0:59 Force theme, e minor, horn, 1st phrase only
0:59-1:53 Luke and Leia, cellos, E major, as Leia and Luke's force ghost converse and hold hands (but I thought Luke, as a ghost, couldn't physically touch anything – that's why Luke's and Ren's lightsabers never touch during their battle...)
1:53-2:03 incidental poignant strings
2:03-2:17 Han Solo and the Princess, viola?
2:17-2:33 incidental do-so-me-do motive (heard in trailer) as Luke's Force ghost heads out to face Ren.
