Dear User,

I am very curious why an artist would need to detect vibrations...

Anyways, what you may find useful is a piezo-electric vibration sensor. You 
can either buy one or make one out of an old piezo-electric buzzer. The 
sensor can be placed under a long rod with a small lead weight on the end 
(resonator). There is a variety of simple electric schemes which can 
amplify the output of the sensor.

Hope it helps,
