Sugar pine is used for the "trackers" on some pipe organs.  It is light
and has less inertia that some woods, and may have properties regarding
stability with humidity changes.  The D.A. Flentrop (Netherlands) organ
in Seattle, built in the early 1970s, used Oregon sugar pine for
connecting the keys to the valves, and as I remember, in some parts
of the organ the tracker is 15" long.
