After completing her studies, she returned to Derry in 1930. Later that decade, she settled in Belfast, where she resided for most of her working life.[3]
Between 1930 and 1960 Parke taught music in Belfast and worked as a composer.[4][5] Among her pupils were Norma Burrowes, Derek Bell,[5]Kenneth Montgomery and Marjorie Wright - all of whom had high regard for Parke.[3]
Her husband, Douglas Brown, was a teacher and accomplished musician in his own right.[4] Parke and Brown frequently performed concerts as a piano duo. She also performed with fellow Belfast musicians Howard Ferguson and Havelock Nelson.[3]
Parke taught in Belfast for fifty years, before eventually retiring to Portrush, County Antrim. She died in Portrush on 15 February 1990.[3]
Parke is primarily known for her compositions for children, set to poems by Ulster poets. They have been described as "simple tunes with strong rhythms", and are still popular throughout Derry. During her lifetime, her music was performed over thirty times on RTÉ Radio and BBC Radio.[3]
Parke wrote over 150 compositions[3] - including songs and piano solos, choral and vocal music[5] - though only a few are still performed today.[6] She also composed a substantial amount of piano and chamber music, many of which remain largely unknown and overlooked.[3]
Her compositional style has been compared to English composers Ralph Vaughan Williams and Herbert Howells; "very approachable but of a rather naïve simplicity and with ingenuous harmonies".[4] Sarah Burn has praised the value of Parke's music:
Nevertheless, her music is distinctive and always effective; many of her choral and vocal settings in particular, archive a real poignancy and show considerable expressiveness. She did occasionally use a more advanced idiom, as in her choral settings of Chesterton and Stephens.[4]
Parke won composition prizes at the Royal Academy of Music and the Dublin Feis Ceoil. She also won the Londonderry Music Festival's Knockan Cup for composition, four years in a row.[3]
