In Freundschaft
In Freundschaft (In friendship) is a composition by Karlheinz Stockhausen, number 46 in his catalogue of works. It is a serial composition for a solo instrument, first for clarinet, and later arranged by the composer for many other instruments, often in friendship to specific performers. In Freundschaft was first conceived in 1977 as a birthday present for clarinetist Suzanne Stephens, and was first performed at her birthday party in Aix-en-Provence on 28 July that year in a version for the flute. It was later reprised on other instruments as the composer adapted it to nearly every standard orchestral instrument at the request of performers. The work is an example of formula composition, with a basic motif first being presented and then varied in two contrasting, cyclical layers; interrupted by cadenzas. The work has been recorded multiple times, including under the supervision of its composer. Background The works by the prolific composer Karlheinz Stockhausen have been grouped in four phases, with the first two matching the decades of the 1950s and the 1960s, the third phase ranging from 1970 to 1977, and finally the rest of his life, dedicated mainly to the composition of Licht, an opera cycle in seven parts begun in 1977. During the third phase, Stockhausen composed in a technique that he termed "formula technique" (Formeltechnik), with works including Mantra (1970), Inori (1974), Jubiläum and In Freundschaft (both 1977). He included the formula method in other compositions of the time such as Tierkreis (1975/76). Composition history The first version of In Freundschaft was composed on Sunday, 24 July 1977 in Aix-en-Provence as a birthday gift for Suzanne Stephens. This version was written for the clarinet, but Stockhausen immediately made a fair copy transposition for flute, and it was this version that was first performed, one time each by two American flautists, Lucille Goeres and Marjorie Shansky, for Stephens's birthday party in Aix on 28 July 1977. The first public performance, also of the flute version, was given by Lucille Goeres on 6 August 1977, in a concert by course participants of the Centre Sirius at the Aix Conservatory. Stockhausen reworked the composition on 27 April 1978, at which time he also made versions for oboe, trumpet, violin, and viola. The premiere of the version for clarinet was given by Suzanne Stephens on 30 November 1978 as part of a concert Hommage à Olivier Messiaen, in the Salle Wagram, Paris, and the version for oboe was premiered by Heinz Holliger on 6 July 1979 in a concert themed Music of the 20th Century in the large hall of the broadcaster Saarländischer Rundfunk in Saarbrücken. At around this time, Stockhausen adapted the clarinet version for the basset horn, with extended range to low C3, and this version was first performed by Stephens at a private gathering at the composer’s house on the occasion of his fifty-first birthday on 22 August 1979. Both the clarinet and basset-horn versions are authorised for performance on bass clarinet, and the first public performance of
