VIBRAPHONE THeORIES

Vibraphone Theories is a set of three rhythmic pieces for vibraphone and sine tones interference beats. The sine tones are played as a stereo electronic music part during a live performance. Microtonal intervals in the sine tone part create amplitude beats, which have been sequenced to create the rhythms notated in the score. When the vibraphone plays notes close in pitch to notes in the sine tone part, additional beating is created. The similar timbres of the vibraphone and sine tones are blended together to sound like one instrument, where the interference beats sound similar to vibrato.  

Vibraphone Theories was performed by Kroumata in Sweden for the 2009 International Society of Contemporary Music (ISCM) festival. This piece was also recorded by Portuguese percussionist Nuno Aroso for his CD Technicolor. It has since been performed in New York by Sean Statser in an ExhAust concert titled 'Sine & Syrinx' (2013) and by Daniel Pate in the New York City Electroacoustic Music Festival (2016).

GLOCKEN BLOCKEN

Glocken Blocken is a rhythmic and energetic percussion solo that combines Marimba and Almglocken (cowbells). Similar phrases are played on the Marimba and cowbells, highlighting the differences in pitch and timbre between the instruments. The cowbells are slightly out of tune, which creates a microtonal variation of the same material played on the marimba.

Glocken Blocken was premiered by percussionist Claire Edwardes at the Sydney Conservatorium in an Ensemble Offspring concert. It has since been recorded by Claire at the ABC recording studios and has been released on her CD 'Kammerbox'.

 

 Marimba and Cowbells set up for Claire Edwardes' performance of Glocken Blocken' at the National Portrait Gallery, Canberra, 2017.

LOOM PATTERNS

Looms Patterns is a contemporary piece for portative organ and an electronic music part made from sequenced sine tone interference beats. The piece has a rhythmic grid of 12 pulses per bar, which acts as a loom for the rhythmic and melodic patterns to be woven through. The electronic music part uses the same pitches played in the organ part and extends the limited range of the instrument. The precisely tuned electronic music part contrasts the unstable pitch and tone of the portative organ and at times may create additional interference beats between the live and electronic music parts.

Loom Patterns was premiered at the Art Gallery of NSW by Bree Van Reyk in the 'Music in This Stillness' concert in the Art After Hours concert series. All pieces in the concert were associated with or inspired by the famous  French 'Lady and the Unicorn' tapestries displayed at the time at the AGNSW. Loom Patterns was commissioned by the AGNSW.
