Slip stick motion and a glass harp (singing glasses)

[fizzyfiz]

Homework Statement

Hi! I am writing an IA in physics about singing glasses. I found an explenation for mechanism of producing sound that it is caused by slip-stick motion. I tried to search in google for more information about it but most of the authors seem to not know what they are writing about. Can you recommend me literature which will help me or explain to me the mechanism of slip-stick?

Relevant Equations

Is there any?
