MODELING METHODS FOR THE HIGHLY DISPERSIVE SLINKY SPRING: A NOVEL MUSICAL TOY
Julian D. Parker, Henri Penttinen, Stefan Bilbao, Jonathan S. Abel · 2010
The ’Slinky’ spring is a popular and beloved toy for many children. Like its smaller relatives, used in spring reverberation units, it can produce interesting sonic behaviors. We explore the behavior of the ’Slinky’ spring via measurement, and discover that its sonic characteristics are notably different to those of smaller springs. We discuss methods of modeling the behavior of a Slinky via the use of finite-difference techniques and digital waveguides. We then apply these models in different structures to build a number of interesting tools for computer-based music production.
