Elke Baker gave the following details of the band's composition over time in <<https://my.strathspey.org/dd/issue/3665/|issue 3665>>:

> Terpsichore typically plays in a trio configuration with Elke Baker (fiddle) Liz Donaldson (piano) Ralph Gordon (bass and cello).

>While our earliest recording (Terpsichore Scottish Dance Music 1993) features the duo configuration with just Elke and Liz, our subsequent recordings and usual performance practice feature the trio configuration with Elke, Liz, and Ralph.
