Just Calls for Brass
A second musical layer in the piece makes use of the wide collection of musical robots capable of producing pitched sounds, often not conforming to the standard A=440Hz tuning in equal temperament. These include <Vacca> and <Vitello>, two cowbell playing robots; <Belly>, a carillon; <Harma>, a reed organ tuned to A=435Hz and hence 20 cents low; <Vibi>, a vibraphone tuned to A=442Hz and hence 8 cents high; <Tubi>, <Xy>, <Puff> three quartertone instruments in 24-tone equal temperament (A=452Hz for the quartertones, or 50 cents high).
The composition is entirely embedded in software written within the framework of my <GMT> programming language and its extensive harmony libraries. It cannot be performed by human players. The duration can vary between 4 and 8 minutes. Some aspects of the piece can be controlled in real time: the tempo as well as the balance between the four brass instruments. The four robots for which this piece was performed are shown in the pictures below:
'Just Calls for Brass' was premiered in a first public try out on 18th of December 2008 by the author and his robot orchestra, as a tribute to La Monte Young, one of the founding fathers of the fluxus movement.

This piece is compiled in m_robots.exe. After selecting the required ports (midi or UDP), select the <Korn> robot in the GMT menu. The piece is started by checking the 'BrasCall' task in the cockpit. It runs completely automatic and no user intervention is required. The duration is circa 6 minutes, but may vary from run to run.
