Sinta Wullur was born in Bandung, Indonesia (1958). here she grew up with the classical piano music of her mother, a pianist with a flourishing lesson practice. When she was ten she moved with her parents to the Netherlands.

Her musical training began at the Sweelinck Conservatory in Amsterdam, where she studied piano with Willem Brons from 1976-1982.

At the conservatory, she encountered the Javanese gamelan of Elsje Plantema which was installed here.

She continued her music studies with a study trip to Bali (1983). Here she learned to play various gamelan genres, which led to the founding of two gamelan groups: gong kebyar Tirta (1985) and gendèr wayang ensemble Irama (1987). Together with Henrice Vonck she organized many  projects with well-known Balinese artists.  

From 1985 Sinta studied composition at the Sweelinck Conservatory (Amsterdam) with Ton de Leeuw. She continued her studies with Louis Andriessen and Theo Loevendie at the Royal Conservatory (The Hague). Since 1986 she has been composing for various ensembles and festivals at home and abroad.

In order to realize her wish to integrate the Indian raga and tala systems in her compositions, from 1989 to 1995 Sinta took lessons in Indian vocal music; dhrupad with Uday Bhawalkar and khayal with Koustouv Ray. 

In the period 2014 - 2016 she undertook study trips to Calcutta to further her Indian singing with Sanchita Chowdury. 

Through her affinity with and specialization in linking eastern and western music cultures, Sinta is a popular speaker at conferences and seminars for composers worldwide. She has given presentations in the Netherlands, Bulgaria, Japan, New Zealand and Indonesia about the musical bridging of cultures.
