This device makes use of electro-magnets to actuate ferrous materials, such as a steel string or plate. This allows for an instrument to be played without coming in physical contact with it. This is similar to an e-bow, but with a much more focused range allowing for a more intense actuation of specific frequencies. Using this technique, we can explore the harmonic content of any ferrous material and use it to influence our relaxation practices.
To do this, we will use materials from an electric bass, which are essentially:
All these materials are available on Amazon.com (maybe not the wood)
First off, let's get some supplies:
I tend to gravitate towards lower frequencies so I chose to use electric bass strings, but you can use guitar strings if you prefer. Guitar strings would provide higher pitched and "brighter" tones, while bass string allow for lower pitched "warmer" and "rounder" tones.
String tuning peg + Monorail Bridge
We need a mechanism to tension the string. Since we are only using one string, let's use a monorail bridge system and a single string tuning peg.
