Schiemer, G. M. (2008). Mandala 8 for Bluetooth-enabled mobile phones [Performance]. International Conference on Digital Audio Effects DAFx-08, Helsinki University of Technology, 1 September.



Research Background
Mandala 8 is a performance of microtonal music produced by an ensemble of 4 Bluetooth-enabled mobile phones and was composed by writing software (Scala, Pure data and Java).

Research Contribution
Mandala 8 extends and consolidates the form of wireless interaction Schiemer developed between members of a mobile phone ensemble using a simple graphic score designed to minimise the time required by novice performers to learn the piece. Mandala 8 combines aspects of every work produced in the series since 2005. It explores melodic features of the same 35-note per octave microtonal scale first used in Mandala 7 (Singapore, 2008); uses peer-to-peer networks allowing pairs of players to work in tandem (Mandala 6, presented in Los Angeles, 2007); uses a 4-bit gray code for sequencing musical events and facilitating performer interaction (Mandala 4, Paris, 2006; and Mandala 5,New Orleans, 2006); and incorporates the hocket algorithm Schiemer developed for synchronising independent melodic movement between players in Mandala 3 (London, 2005).

Research Significance
Mandala 8 was initially invited for presentation at the inaugural mobile workshop held at Stanford University in January 2008 where researchers from Stanford University, The Helsinki University of Technology and Deutsche Telekom launched the first mobile phone orchestra with subsequent acknowledgement of the work undertaken from 2003 as part of a Discovery Project. Mandala 8 was subsequently invited for the official opening of the 2008 International Conference on Digital Audio Effects at the University of Helsinki, Finland, where it was premiered on 2 September.
