Stephen Altoft is dedicated to the creation of new repertoire for the trumpet. As a solo artist, and with percussionist Lee Ferguson as duo Contour, he has given concerts throughout Asia, Europe, the United States and Canada. He is a member of ensemble chronophonie (Freiburg) and ensemble linea (Strasbourg). Stephen was also trumpeter in the Music theatre production, “Niebla” by Elena Mendoza and Matthias Rebstock (2007-9) at the Festspielhaus, Dresden, Berlin Konzerthaus and Teatro del Canal, Madrid. In 2014 he appeared at the American Festival of Microtonal Music in New York, the “Bending Brass” event at the New England Conservatory, Boston, USA, organised by the Boston Microtonal Society and at the Daegu International Contemporary Music Festival, in South Korea.
Stephen studied at the University of Huddersfield (1991-5) where he was awarded B.Mus Honours and Masters degrees (in performance) and the Ricordi Prize for Contemporary Performance. This was followed by periods of private study with Markus Stockhausen (Cologne 1996-8) and, with assistance from the Music Sound Foundation, with William Forman (Berlin 1998-1999).
Between 2001-2, Stephen was a consultant for the Centre for New Musical Instruments, London, where he tested a prototype microtonal trumpet. During this time he began working on a microtonal trumpet manual with composer, Donald Bousted, now available here as an online resource. After further research, Stephen developed, in collaboration with Johannes Radeke and Siegmar Fischer (Musik Gillhaus) in Freiburg, Germany, a fourth (rotary) valve mechanism to enable the conversion of his existing trumpets into microtonal instruments (a 19-division B flat trumpet and quarter-tone C trumpet).
Stephen has recorded for radio and televison (SWR, WDR, Deutschlandfunk Köln, Deutschland Radio in Germany, BBC Radio 3 in the UK, France 3 and Bulgarian National Television) and for the Budapest Music Center (Peter Eötvös), Microtonal Projects, Edition Wandelweiser and Wergo labels.
As an improviser, Stephen collaborates regularly with Lee Ferguson (duo Contour), Thomas Wenk (piano, prepared piano, cassette recorder), Harald Kimmig (violin), Ephraim Wegner (laptop) and plays in the Human Factory Band. In 2013 he began working with Jihye Kim (violin). He has also appeared in duo with Gabriele Reuter (Dance).
In 2013, Stephen began formulating concept pieces for performance on the 4-valve trumpets he developed as part of his microtonal work. This lead to the development of graphic scores, which are re-interpreted with each performance, using improvisational techniques. The series of studies explore the possibilities offered and limitations imposed by the converted microtonal trumpets, in combination with contemporary playing techniques.
Stephen teaches at the Waldkirch Musikschule near to Freiburg, Germany. He has also been Trumpet and Brass Tutor at the Bisyoc Summer Course since its inception. In 2009 and 2010 Stephen was trumpeter (ensemble linea) on the Royaumont Composition Courses in France, where he has worked alongside Brian Ferneyhough, Isabel Mundry, Misato Mochizuki and Liza Lim with student composers. He will also be teaching on the new Summer Academy that ensemble Linea inaugurated in Strasbourg in 2014.
