Gaven Dianda has constructed his own gittern: a broadly lute-shaped instrument with three melody strings, three drone/rhythm strings, pythagorean fretting, and a slightly 'sweetened' third. Gitterns are distinct in sound and shape from both guitars and lutes, despite an etymological relationship between gittern and guitar. Gaven also plays the citole, a related instrument with a distinctive 'holly leaf' shape and, in this case, a purer pythagorean third.
Eleanor Verrette performs on the vielle, a medieval forerunner of the violin/viola, with several variants in tuning, shape, bow style, and number of strings. Typically strung with gut strings (although Eleanor is also experimenting with horsehair) the flatter bridges lend themselves to use of 'attack' and drone, appropriate for modal repertoire. Eleanor also performs on the smaller, boat-shaped rebec.
When not singing, Tricia Postle sometimes joins the ensemble on psaltery, in a number of shapes: trapezoidal, step, or 'pig-snout'. The psaltery is a type of zither, with a huge number of variants in modern use: relatives include the arabic qanun, the autoharp, and the soundboard inside a piano.
