Performance instructions:  
1) This piece is unconducted. 
2) There is no score. All notated material is within each performer’s part. 
3) It is anticipated that the orchestra will be positioned in a conventional manner, but the nature of the music and performance also lends itself to new spatial configurations, should these be appropriate.  
4) All instrumentalists play independently of each other. The composer treats each performer as a uniquely independent voice.  
5) Music is cued only at the start when all stopwatches are synchronised. There are no other points of ‘fixed’ synchronisation between the instrumentalists.  
6) Whilst the relationship of each instrument is somewhat flexibly placed against its neighbour, care has been taken to calculate potential outcomes of coincidence and variability. To this end, it is vital that metronome markings and timecode are adhered to as accurately as possible throughout the performance.    

The Score and Parts: There is no score for this orchestral work. All musical material and instruction are fully notated within each player’s individual parts. Adherence to timecode ensures that the architecture of the piece remains intact, but the on-going interpretation of tempi and timecode creates contextual changes to the alignment of musical detail between all the parts. As such, there is no definitive performance; the music has to be performed or experienced to be ‘known’. 
 
Timecode: Timecode is not used to imply the use of any kind of click-track in performance or to be seen as a straitjacket to flexible performance within the orchestra and timecode framework. However, players are required to use individual mobile phone stopwatches during the performance to help structure timings, prevent long-term tempo-drift and delivery of their material to achieve an outcome that most closely matches the composer's structural intention. Continual reference to the timecode embedded in each part when read in reference to the stopwatch is particularly useful after longer pauses or where tempo has slipped due to playing under or over the metronome markings, enabling the performer to compensate by playing a little faster or slower to 'catch up' or extend or cut short pauses and rests as necessary to remain broadly on track with the timecode throughout the piece. It is important to start and also complete phrases within and as close to timecode parameters as possible. Please adjust your playing speeds continually to align with the timecode.

Marc Yeats is an internationally renowned composer and visual artist whose compositions have been performed by the most noted of orchestras and ensembles across the globe. These include UK companies such as The London Sinfonietta and The Scottish Chamber Orchestra, the BBC Philharmonic and the Halle Orchestra and Chorus. Further afield, Marc’s work has also been performed by the Tokyo City Philharmonic, the Atlanta based, Chamber Cartel, and many others. His compositions have gained great acclaim through many radio broadcasts for the BBC and also been broadcast in many other countries including the US, Germany and New Zealand.

Marc’s relationship with the BBC is both strong and enduring, starting with a BBC Scotland performance by the Edinburgh String Quartet more than 20 years ago. His first orchestral work – I See Blue – conducted by Martyn Brabbins, received much acclaim when first performed around the same time. This led to specific BBC commissions, including a piano concerto to open Piano 2000 in Manchester, with Kathryn Stott as soloist, and a solo harpsichord piece ‘Rhema’, performed by Mahan Esfahani and broadcast in 2010 by BBC Radio 3 from the Clothworkers’ Centenary Concert Hall in Leeds.

Selection as one of just 10 to attend the legendary Hoy Summer School in 1994 brought Marc into contact with the late Sir Peter Maxwell Davies. At the completion of the course, Max was keen to support and promote Marc’s work, and conducted his first commission with the Scottish Chamber Orchestra at the St. Magnus Festival in 1997. He and Marc continued to share ideas, and Max took a great interest in Marc’s visual art and compositional work with mobile technologies and a range of asynchronous structural approaches to composition.

Marc is excited to have recently been appointed composer-in-residence to Yeovil District and Dorchester County Hospitals, a position he has also held with other UK and US organisations. Work such as My Blood Is As Red As Yours’ (an orchestral and choral piece commissioned by the Halle to celebrate World Aids Day in 2008 and performed at the Bridgewater Hall) and recent work, such as ‘shapeshifter’ and ‘the observation quartets’ continues to enhance his reputation as a leading contemporary composer.
