Abstract: A finger guide for a clarinet has two substantially rectilinear rods that are connected by an offset-rod portion that holds the two rod portions in offset positions. Mounting posts on either end of the rectilinear rods fit in a sleeve extending radially from ring clamps that mount the finger guide on the clarinet. This allows the finger guide to be mounted with one rod portion on one side of a reference plane through the axes of the rest-position tone holes while the other rod portion is positioned on the other side of the reference plane. Tongue portions extend outward at the longitudinal positions of the little-finger keys to provide guidance for the little fingers.
