There's kind of a cool feel that happens every now and then. I guess that feel is the thing that makes the score its own score. But, I don't know exactly what that is. So, it's hard for me to answer that question.

Danny Elfman’s quote reflects on the elusive nature of creating a unique score for a film. By saying, "There's kind of a cool feel that happens every now and then," he refers to the special, intangible quality that can emerge during the composition process. This "feel" is something that transcends just technical music-making and speaks to the emotional or atmospheric impact a score can have on a film. Elfman acknowledges that it's hard to fully understand or describe this phenomenon, which makes it difficult to pinpoint exactly what makes a score stand out.

The quote also reveals the mystery behind the process of composition. Elfman admits that he doesn't fully know what causes this special element to emerge, but recognizes its importance in defining the identity of a film’s music. This speaks to the creative process in general, where certain elements of art or composition cannot always be explained or articulated, but are instead felt intuitively during the work itself.

Elfman’s uncertainty about this "cool feel" shows the complexity and unpredictability of crafting music that is both distinctive and memorable. It highlights the personal nature of composing a score, where sometimes the magic comes from moments that aren’t planned or fully understood. The artistic intuition involved can be difficult to express in words but is deeply felt in the final product.

In essence, Elfman’s quote reflects the mystical side of music composition, where certain moments come together to create something greater than the sum of its parts. It emphasizes the idea that the best scores often have an indefinable quality that gives them their own unique voice, and even the composer can’t always explain how or why that happens.
