Wind chimes
Daytime or nighttime
   On the hour: the sound of a small wind chime is heard, as if a breeze has just blown through the room.
   The chime that was recorded has short (4-6”) brass tubes, so the sound is high and twinkling.
   Following the chime, the largest tube is played several times to “count” the hours (4 tones at 4 o’clock, for example).
On the quarter hour: two small chimes are heard.
