Often considered the spare part instrument or the the one to give the singer so they can 'join in', the tambourine actually plays an important role in rhythm with it's unique sound that spans across all genres and cultures.
It doesn't have to be used incessantly (as Chris Martin tells an eager fan!), although being tasered for using one certainly seem harsh, but from The Beatles to Motown to Florence + The Machine the power of tambourine will continue to slip under the radar.
Here's my 6 part appreciation:
1. The perfect intro:
Jets Overhead - Boredom and Joy
Jet - Are You Gonna Be My Girl
Lupe Fiasco - Daydreamin'
2. Dictating the tempo
The Beatles - Day Tripper
Gwen Stefani - The Sweet Escape
Jackson 5 - The Love you Save
The White Stripes - The Denial Twist
Florence + The Machine - Shake It Out
3. Keeping rhythm during quieter parts
4. Power and Echo
5. Adding percussive depth and layers
6. Accentuating the snare drum
