Whistling and Proper Breathing Improves Health?
Angry People = Miserable Lungs
Is this why these songs are so fun? When hear them, do they make you want to whistle along? Does this make you feel good? Do the artists use natural or synthesized whistles in their songs?
Britney's whistle is a sample. It was also used in a 3OH!3 song featuring Katy Perry Starstrukk. It has now also become a widespread ringtone. http://www.britney.com/us/forum/i-wanna-go-whistle-sample
Pumped up Kicks whistle is legit. It is infectious and will make you damn healthy as it is hard to stop whistling the tune. http://musicforants.com/blog/?p=7384
In conjunction with the American talent show The Voice, Maroon 5 and Christina Aguilera performed this song live on the show as the release. The whistle drives the melody. The song is reminiscent of the 1978 Rolling Stones #1 song "Miss You" where the melody is driven by a unique 'woo hoo' composition and not a whistle. The whistle in Moves Like Jagger sounds natural until the end when it skids out.
Ryan Tedder of One Republic says, "We have this REALLY super simple whistle. I hadn't heard a whistle in a song in forever and that's all I kept hearing on the song so I just whistled this melody into the mic and it really is the hook — it's the catchiest part of the song. http://www.songfacts.com/detail.php?id=21724
