Here's a very peaceful device I got from James Newton Howard's score to "Peter Pan". It's a great score and I'll definitely grab some other cool sounds from it. Even though I'm not really a fan of the Peter Pan movies in general, it seems like the soundtracks are always stellar. Do yourself a favor and check out the following:
1) Tinkerbell and anything else P.P related by Joel McNeely.
2) James Newton Howard's "Peter Pan".
3) Benjamin Wallfisch's "Peter Pan".
4) And of course, the one that sets the bar (veeeeery high I might add) : "Hook" by John Williams.
The device itself is a woodwind melody with the choir in a slightly different pattern, accompanied by strings and harp. The glock is sort of a combination of the two melodies in the woods/choir, it's purpose is to highlight some notes and add a little sparkle.
Here's the sketch:
