Brandeis, HansHans Brandeis "Hans Brandeis is an ethnomusicologist by profession, with a main interest in the traditional music of the Philippines. His favorite musical instrument there are the boat lutes (kutiyapi, kotapi, hegelung, faglung, kuglung, etc.), which can be found among all the ethnic groups of Mindanao and Palawan. Between 1976 and 2014, Hans Brandeis made 15 research trips to the Philippines, comprising almost 4 years of ethnomusicological research. During these trips, he documented the music traditions of the mountain tribes of Mindanao island, recorded about 130 hours of vocal and instrumental music as well as various ceremonial performances on analogue and digital audio tape, another 60 hours on digital video tape, and he took almost 8,000 photographs. Portions of his recordings were transcribed and translated on about 2,000 type-written pages. He also collected more than 400 musical instruments from all over the Philippines. Most of these materials are now part of the collections of the Ethnological Museum Berlin. Copies of a major part of the sound recordings are also archived with the College of Music of the University of the Philippines, Quezon City, and with the Folklife Museum of Xavier University, Cagayan de Oro, Philippines. About 300 musical instruments are kept at the archives of the Musical Instruments Museum (MIM) in Phoenix, Arizona, another four with the Musée du quai Branly in Paris. Analyses of some of these materials were published in scientific publications. Hans Brandeis became interested in the Philippines, because his sister had married a Filipino and lived in Manila for more than 15 years. During one of his early trips, Hans Brandeis met his Filipina wife. He and his family are actively involved in the work of the Filipino community in Berlin. Since 2014, Hans Brandeis has been retired, but is still continuing his research on the traditional music of Southeast Asia. ..." - https://boatlutesofthephilippines.weebly.com/about.html, 05.01.2019
