Sahakdukht and her brother Stepanos Siunetsi [hy], who became a noted composer and music theorist, were educated in Dvin.

She then spent her life as an ascetic, living in a cave (a grotto) of the Garni valley where she wrote and taught music.

[4] Active in the early 8th century, her brother was the composer and music theorist Stepanos Siunetsi [hy],[2] known for his sharakans (canonical hymns).

[1] She purportedly wrote many now-lost Christian religious compositions, including ktsurds (antiphons and anthems), sharakans and other melodies.

[1] Sources say that such works were often written for the Virgin Mary, making them roughly equivalent to the contemporaneous Byzantine tradition of theotokions.

[10] This may be explained by the fact that Stepanos lived in Constantinople for many years, where Germanus I, an important proponent of early kanons, was active.

Some scholars, including Ghevont Alishan, Malachia Ormanian and Grigor Hakobian attribute Khosrovidukht's sharakan "Zarmanali e indz" to Sahakdukht instead.

[5] In addition, according to historian Agop Jack Hacikyan, phrases appearing in "Srbuhi Mariam" such as "incorruptible temple," "ray of divine light," and "tree of life" have since become standard and popular in Armenian religious poetry and music.

Հաստատութիւն երկնի և երկրի, Կենդանութեանց բաշխող, Որ աստուածային լուսով ճառագայթիւքըն վայր իջեալ՝ Վերականգնեաց ըզնախահայրն ի գլորմանէ.

Կենացն փայտիւն հորդեցեր մեզ ճանապարհ Ի սրովբէափակ պահպանութենէ Եւ զբոցեղէն ըզսուրըն կապտեցեր.

Հիւթական, եղական, անեղ բանին բընակարան, Որ ըզհուրն աստուածութեան Յորովայնի քում ընկալար և ոչ բոցակիզար Որպէս որմըն ըզմորենին, Այլ ծնար զաստուածըն բոլորից.
