With the increased usage of microtones by contemporary composers, research is needed into the various systems currently in use along with other potential ways of constructing musical temperaments. Considerations need to be made regarding the performance practicalities of such systems, especially when used on conventional orchestral instruments with limited means of producing unconventional intervals. The harp is an instrument which is confined to equal temperament and therefore is problematic for composers wishing to use alternative tuning systems. This article looks at the possibility of creating a microtonal harp using an older version of the instrument and describes a new tuning system proposed by Sturman (

) using a non-linear circle equation. The article outlines the details of this tuning system and how it fits with the triple harp. It then explains some of the practicalities involved in the process of composition using this unusual tuning in conjunction with the traditional instrument.
