There is a particular piece of music from Star Trek that I'd like to be able to identify by name. The one example I could find quickly is from The Mark Of Gideon. It's when Kirk and Odona are on the bridge and Kirk is asking her to explain why her people want to be alone. On the BD version I have, the music starts at 23:30 into the video. It's at that same time on the video on Daily motion. It starts after Kirk asks, "What makes it so impossible to be alone?" and when Odona answers.
This piece is used on a number of episodes and even though I have some of the soundtrack CDs from the original series, I have not been able to find this piece on any of them. Does it have a title and is it part of any collection that can be purchased or downloaded? And is there any extra information or any trivia points about this short piece?
