Curriculum vitae

Rokus de Groot (*1947 Aalst, Netherlands), musicologist and composer, conducts research on music of the 20th and 21st centuries, especially in the field of aesthetics and techniques of composition, and in the field the interaction between different cultural traditions, particularly in the perspective of present-day (re)conceptualisations of past and present religious and spiritual traditions in relation to music. He also has published on Edward Said and polyphony/counterpount, in the musical sense, as a metaphor and as an intellectual mode.
He obtained his MA in musicology with honours at the University of Amsterdam (Frank Ll. Harrison, Ton de Leeuw) and his PhD at the University of Utrecht (Paul Op de Coul, Jos Kunst). As a musician he received teaching from Cor Visser and Willem Vogel (organ) and Ernst Heins (Central-Javanese court gamelan). He obtained a diploma of cantor-organist in 1969.
He holds the chair of musicology at the University of Amsterdam, after occupying a personal chair 'Music in the Netherlands since 1600', at the University of Utrecht (1994-2000). In 1993/4 he was a fellow at NIAS.
In 2009 he was visiting professor at the American University of Cairo (AUC), Dept. of English and Comparative Literature, and in 1992 and 2003 at the Universidad Nacional Autonoma de Mexico in Mexico City.
On the invitation of American University of Cairo, he delivered the Edward W. Said Memorial Lecture 2009, 'Contrapuntal Intellectual: Edward Said and Music'.
In 2011, he was invited to participate in the Eranos Meeting at Ascona, organised by the Fetzer Institute, on the theme of "Love and the Musical Arts". The Eranos meetings were initiated in 1933 by Olga Fröbe-Kapteyn, with support of Carl Jung. In the same year he also addressed the International Symposium of the Institute for Cultural Diplomacy, Berlin, "The language of art and music", on the theme of polyphony as a social and a political mode of thought and action. Also in 2011, he was invited by the Asisatic Society, Kolkata (Calcutta), established in 1784 by Sir William Jones, to deliver a presentation at its international conference commemorating Rabindranath Tagore's 150th birthday.
He has given lectures and guest courses at universities and music institutions in West- and East-Europe (a.o. Charles University, Prague; Music Academy of Belgrade, the Conservatories of Moscow, Athens, Ghent and Tirana), India (Delhi at ARCE; Mumbai at the University of Bombay and NCPA; Chennai at Prakriti Foundation, Banares at Hindu University; Kolkata at Asiatic Society), the Americas (UCLA, Universidad Nacional Autónoma de México) and South-Africa (Johannesburg, Witwatersrand), about intercultural exchange, about Western compositions based on musical models from Indian and Turkish classical traditions, as well as about the history and theory of Western music.
From 2004 to 2008, with a team of researchers, includingBurcht Pranger, Sander van Maas and Jael Kraut, he was workingonthe project 'New Music and the Turn to Religion', which is part of the Dutch research program The Future of the Religious Past.
He was co-organizer of international conferences at which the subject of music and spirituality was a central issue of discussion, likeMusic, Poetry and Devotion (Utrecht 1998), New Music and Spirituality (Amsterdam 1999), The Arts and Ideas of Rabindranath Tagore (Amsterdam 2001). In 2000 he was one of the organisers of the conference 'Choices in New Music', involving ensembles, orchestras, publishers, organisations of composers, artistic policy, subsidisers, documentation, and promotion (Amsterdam). Under the title 'Redefining Musical Identities' he co-organised several national and international seminars and conferences (Amsterdam 2001, 2002, 2004). In 2004 he co-organised in Amsterdam the International conference Modernity and postmodernity in musicand visual arts in the Middle eastand North Africa, in cooperation with Musicin ME and Foundation Gaudeamus, with participationof the NWO-program The Future of the Religious Past. His Department of Musicology supported the international conference India-Iran: Confluence of musical cultures, held in January 2005 at NCPA, Mumbai, India, as well as Music and the Art of Seduction (Amsterdam, May 2005). In 2006 he co-organised the international conference Cathy Berberian: Pioneer of Contemporary Vocality and Performance, with the Amsterdam School for Cultural Analysis, and in 2007 the international conference Spiritual New Music: Between Fall and Resurrection (NWO, ASCA). For the Tagore conference he wrote the composition Hide and Seek, for mezzo soprano, baritone and piano, on a text from Gitanjali. Together with Theatre Studies and Musicology of the University of Amsterdam, he co-organised the Symposium Edward Said: Academics, Activism, Art, in 2010. In 2011, Elmer Schönberger (ASKO/Schönberg) and he, with support of Muziekgebouw aan 't IJ, invited an international team of scholars at the Symposium Galina Ustvolskaya: New Perspectives.
He has conducted field research in Scotland (1971) and North India (1992, 1997), in the latter case on present-day interpretations of the legacy of the 16th-century mystic poetess Mirabai.
During the celebrations of the 50th Anniversary of Indian Independence in the Netherlands in 1997 and 1998, De Groot organised music and dance performances, as well as university seminars around Mirabai, who was one of the key figures of these celebrations. He published abook about this Indian mystic, Verliefd op de Donkere (In love with the Dark One, 1998), and composed song cycles on her poetry.
Recently he investigated the role of Rabindranath Tagore in Dutch cultural life since the mid-1910s, studying Dutch musical settings of his poetry.
In his compositions, Rokus de Groot explores the expressivity of melodic contours,and polyphony. Examples of his works are: Kontur for soprano saxophone (1982), Promenades,Marches et Danses, for small orchestra (1986), Winds of a far air, for flute and soprano saxophone (1991), In Love with the Dancer: Songs of Mirabai I for soprano or tenor solo (1993), Tide of seasons, for windquintet, string quintet, piano and percussion (1995). He also wrote a piece for Turkish ud and Western ensemble, Seyir, which was performed in the context of a Turkish lute project, co-organised by the Conservatory of Amsterdam and the Department of Musicology, University of Amsterdam (2001).
Later he has composed a second and third cycle of Mirabai songs, I have torn off the veil of worldly shame (1997), and The story of the Mirabai's poisoning(1999). He wrote the music for dance performances on a text by Marc Chagall on the 'Song of songs' from the bible, combining the South-Indian dance traditions of devadasis and bharata natyam with Western contemporary music traditions (Amsterdam, Beurs van Berlage, 2000, Theatre of the Royal Tropical Institute, 2002). This composition, Song of songs: The Love of Mirabai was performedduring the cultural program of the 6th India-EU summit in New Delhi, at SAI International Centre, with choreographer and dancer Kalpana Raghuraman (September 6, 2005). Dr Saskia Kersenboom was instrumental in modelling this compositionon the South-Indian varnam.
In 2004 the première was given of Mehfil for piano solo by Ralph van Raat, to whom it is dedicated. This piece is based on the North Indian râga Chandrakauns; various forms of meend (glissando) are projected on the piano, by way of a special technique of pedaling and the holding/releasing of keys.   
In 2005-6, together with the Theatre of the Royal Tropical Institute, he has initiated a festival on the Arabic-Iranian story of Layla and Majnun. Like in Seyir, the concept of mutual learning between musicians from the world of Islam and from the West hasbeen developed. His danced music theatre Layla and Majnun, A Composition about the Night, was premiered on November 2006 in Amsterdam, by the Nieuw Ensemble, Nederlands Vocaal Laboratorium and guest dancers and musicians (breakdance, oriental dance, qanun, 'ud). This performance was realised by dancers, musicians and singers from Europe, Lebanon/Ecuador, Iraq, Turkey, and the U.S.
Part of the Layla and Majnun music theatre was performed in the Poetry International Festival, Rotterdam 2010, with Bassem Al-Khoury, Eduard van Regteren Altena and Haider Al-Timimi. Together with Ashghar Seyed Gohrab, De Groot advised Poetry for Layla and Majnun as one of the Festival Themes.
In December 2009, at the invitation of Park's New Festival of the Prakriti Foundation, his compositions ShivaShakti I and II were performed in Chennai (Madras), featuring Dhruba Ghosh, sarangi, and Ernest Rombout, English horn. ShivaShakti II was also peformed in a very different counterpoint, between Boris Cicovacki, alto oboe, and improvising musician Nebojsa Ignjatovic, double bass, mbira, vocals, a.o. instruments (Belgrade,City Palace, 2012).
His interest in Japanese aesthetics, especially concerning the shaping of kinetic-sonorous gestures, has led to Cantata 6 Gong 'Botan Kuroku' (tenor, 2 violas, cello, piano and gong, 1972), Winds of a far air (flute and soprano saxophone, 1990), and recently Kumo no Utsuroi (shakuhachi, shô, and koto, 2008, premiered in Mallorca). His composition Passing for shô solo was played by Naomi Sato at the first Bach Festival in Dordrecht, 2010.
His compositions have been performed in the Netherlands (Amsterdam, Concertgebouw, Theatre Royal Tropical Institute, Muziekgebouw aan 't IJ, a.o.), Belgium (Antwerpen, de Singel), Spain, Sweden, U.S.A, Mexico (UNAM), Russia  (Moscow). Tchaikovsky Conservatory), Serbia (Belgrade, City Palace), Albania (Tirana, Music Academy) and India (Delhi, SAI Auditorium; Chennai, Kalakshetra Auditorium).  He is the brother of composer Jan Rokus van Rosendael. 
On his retirement from the University of Amsterdam, he received the decoration of honour for special merits of the Faculty of Humanities, which was handed over to him by its dean, prof.dr. Frank van Vree, on May 25, 2012. At that occasion his string quartet, dedicated to the University of Amsterdam at its 380th anniversary, had its first performance.
At this ceremony he also received Liber Plurium Vocum, for Rokus de Groot, ed. by Sander van Maas, Carolien Hulshof and Paulien Oldenhave, Amsterdam: University of Amsterdam, 2012.
