I'm a synesthete so I get quite a kick from sounds. I really like voices. Sounds for me have a definite texture, shape and personality so when I hear music or poetry, I really get swept up by it. Even when a particular actor in a movie has a voice I like, it speaks to me far beyond the words he or she is saying.
The sound of fall. When just enough leaves are on the ground to create that crunch but you can still hear the wind in the trees.
