A must for that great song "intro" ethereal effect. This little whistle measures 2" long and is 1 1/2" at the base. Made of hard black plastic. 5 sound effects in one. 1. Magpie Chatter - cup hand around bowl to muffle the sound and "spit blow" hard to create a chatter. 2. Jay Call - make 2 or 3 long but sharp blows to produce the hiss of the jay. 3. Steam Train Effect - short, sharp, rhythmic blows. Start slowly then increase in speed to mimic the train pulling away from the station. 4. Steam Train Whistle - After train effects, put one finger into half the hole in the bowl. Long drawn out blow produces train whistle. 5. Wind Sound Effects - One long drawn out blow varying the breath pressure to sound like gusting wind whistling around a building. Sound Sample
