An electroacoustic thesis statement in nonbinary performance, HARP+ redefines the modern chamber ensemble by deconstructing sonic and concert stereotypes. Through electronic augmentation, sampling, looping, and live projection, HARP+ explores the relationship between performer/instrument, gender/instrumental stereotypes, and acoustic/electric tone colors.  Sampling ideas from alternative music genres, free improvisation, and contemporary harp repertoire, HARP+’s unique voice ranges from minimalistically smooth soundscapes to dissonant expressionism . 


HARP+ is an award-winning electroacoustic improvisation ensemble comprised of Grace Scheele (Harp/Electronics), Arie van de Ven (Viola/Electronics), and Dave Klassen (Synthesizer). Winners of the Audience Choice Award during the Toronto International Film Festival’s 2019 Next Wave Film Festival and Numus Concerts’ 2017 Emerging Curator Competition, HARP+ successfully self-funded their first Ontario/Quebec tour in September 2018 and debuted to sold-out audiences in Toronto and Montreal.  In May 2019, HARP+ presented it’s award-winning improvisational style at the International Society for Improvised Music’s 11th Annual Conference and Festival. As participants in the 2019 Montreal Creative Music Lab, HARP+ along with composer Kim Farris-Manning co-developed an interdisciplinary comprovisation which utilized live projection, text, electronics, and electroacoustic instruments to explore themes of queer identity and states of being.

// viola, electronics

Hailing from Toronto, Ontario - Arie Verheul van de Ven is a Violist and Composer currently based in The Hague. Arie's viola playing is informed by a fascination of the proprioceptive relationship musical instruments have with our bodies - as well as how changes in this relationship affect the sounds we make. Arie grew up as a suzuki violinist while also studying klezmer and Canadian fiddle styles - joining an improv ensemble led by Kathryn Ladano at Wilfrid Laurier University has led to a lifelong fascination with the scratches, squeaks, and other unpitched noises bowed strings can make. Arie is currently pursuing a masters degree in composition at the Koninklijk Conservatorium in The Hague.
