Tambourine jingles can be purchased on ebay.

Latin Percussion sells $185 tambourines

with a variety of jingles.

Tambourine jingles are made in a variety of materials.

They are made with a dome in the middle and flared

raised rims. The jingles are paired with the domes

facing away from each other and 3 little divets,

pressed in the jingles from the top, travel through

the jingle to create an uneven space between the pair.

In honor of Tesla's advice to keep things in

quantities of 3, 6 & 9

I have the following observation about the

arrangement of jingles and their effect on the sound.
