Any tea lover can tell you, one of the most important tea preparation tools one can have is a simple teaspoon. It is one teaspoon of loose tea, after all, that makes (in general) one cup of tea. In fact, this is why it is called a teaspoon!

However, the humble teaspoon also has another interesting use in a guitar playing technique known as optel and knyp.

Developed by South African guitarist Hannes Coetzee, this technique is similar to a slide guitar, but instead of the traditional bottleneck (not surprisingly, the material original slides were made of was the glass neck of beer or wine bottles), the performer uses a teaspoon that he (or she) holds in his (or her) mouth.

Since a visual is worth far more than mere words, check out this mesmerizing melody using the teaspoon technique here:
