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, A.G.E.
