Summary of the impact
Since 2006 Professor Christopher Fox has been engaged in a series of
linked projects which explore ways in which the engagement of performers
and listeners in texted music for vocal ensemble can be enhanced. The
research was initially based on received understandings of the perceptible
relationship between music and text but, as the project and its impact
have developed, the research has extended into a collaborative scientific
study of this relationship, funded by two successive awards from the
Wellcome Trust. Each stage of the research has been extensively
disseminated through public performance, broadcast, recording, print and
on-line media and the impact of the research now reaches into a wide range
of communities of interest and the general public.
Underpinning research
The research has been undertaken by Professor Christopher Fox and is a
developing project in four main phases, investigating the relationship
between text and music in new composition for vocal ensemble. This
relationship is the subject of a number of longstanding assumptions held
by musicians particularly about the extent to which sung texts are
intelligible.
Fox's initial study, 20 Ways To Improve Your Life, focused on
predominantly syllabic settings of short contemporary texts whose banality
(they were drawn from small ads in free-sheet newspapers) might be
expected to make them readily intelligible. As these settings could also
be heard as a 21st century version of `City Cries', a genre of the 15th
and 16th centuries (cf. Jannequin, Gibbons, Weelkes, etc), the work was
taken up by The Clerks (director, Edward Wickham), a group which
specialises in Renaissance vocal music.
A second pilot study, Sing a new song, juxtaposed different
elements of a text, using the classically-trained voices of The Clerks as
counterpoints to a unison line sung by children. This phase of the project
was funded by Faber Music as part of their work for Sing Up, the
government initiative to encourage singing in schools. Government-funding
for Sing Up was withdrawn in 2011 but its on-line resources remain
available and Sing a new song continues to be used in schools.
A third, more substantial phase grew out of the evaluation of these
initial studies. It was realised that a more systematic investigation was
needed into the degree of intelligibility achieved by each musical
setting. Edward Wickham proposed the Brungart test, an auditory streaming
test devised by the US Air Force to train air-traffic controllers, as a
model and a new work was devised in which voices within a Brungart test
gradually turn into characters in a domestic drama scripted by Wickham. A
successful grant application was made to the Wellcome Trust's `Public
Engagement' funding stream and three scientific advisers — experts in
linguistics and acoustics — were added to the project team. The resultant
work, Roger go to yellow three, is a 25 minute-long performance
within which a number of tests are embedded for listeners to complete as
it progresses.
The data from performances of Roger go to yellow three yielded a
range of new findings about the effects of masking between auditory
streams, summarised in a conference poster by Heinrich, Cross and Hawkins
— `Stream segregation of speech in live concert-hall performances of a
6-voice choir' — and a second, more substantial funding application was
made to the Wellcome Trust for the creation of a work within which further
tests are embedded to investigate these masking phenomena and the role of
harmonic and melodic dissonance in determining listeners' focus. The
application was approved in summer 2012 and the new work, Tales from
Babel, again with a libretto by Wickham, was premiered at the
Cheltenham Festival in July 2013 and toured in the UK in autumn 2013.
The composition of new music is a key element underpinning the research
produced by the Centre for Contemporary Music Practice (CCMP), the Music
Research Centre at Brunel University, and Fox's work is complemented by
similar work being undertaken on new techniques for vocal music by other
members of the CCMP, particularly Harald Muenz and Jennifer Walshe. Fox's
former PhD student, Dr Simon Katan, is also involved in related research
and during the latter stages of the project he built the web-site which
enables on-line participation in the project (see section 5 for URL).
Specific support for this project was provided when The Clerks were
invited to perform an early version of Roger go to yellow three at
the School of Arts' `Researching the Arts' conference in May 2011 so that
the data collection method used in gathering listener feedback could be
tested. Further support was provided through a period of study leave
(academic year 2012-13) for Fox to enable him to compose the music for Tales
from Babel.

Details of the impact
The impact of this project lies not only in the musical works which have
been produced during the research but also in the new understandings which
have been developed as the project has progressed about the ways in which
listeners respond to and understand multiple streams of auditory
information in these musical works and, by extension, in texted vocal
music in general. Performance of the musical works has generated new
hypotheses about auditory streaming and in the latter phases of the
project the testing of these hypotheses has embraced both compositional
practice and scientific investigation, a process enabled by substantial
support from the Wellcome Trust.
Although the impact of the latter phases of this project are potentially
the most wide-reaching and influential, there has nevertheless been
considerable impact at every phase. The initial output, 20 Ways To
Improve Your Life, generated extensive interest through its musical,
textual and social significance. The work was presented and discussed on
BBC Radio 3's The Verb while it was still a work-in-progress; it
received concert and street performances at the Spitalfields Festival and
was recorded by Signum Records for a CD which on release was in Gramophone
magazine's Top Ten for January 2010. It was also heard on the soundtrack
of Channel 4's Dispatches documentary, `The trouble with Boris',
and a new version for mass participation was commissioned by the Greater
London Authority and performed outside the Tower of London.
Sing a new song has been published by Faber Music and is also
available as a download from the Sing Up website. It has been
adopted by a number of schools, particularly in east London and in
Cambridgeshire and was broadcast in BBC Radio 3's The Choir.
The impact of the initial stages of this research were recognised by the
Wellcome Trust when they chose to support the application made by The
Clerks to develop the project further with a grant from the Trust's Small
Arts Award scheme. The impact was also demonstrated by the willingness of
three scientists, Professors Ian Cross and Sarah Hawkins of Cambridge
University and Dr Antje Heinrich of Leicester University, to join the
project team for the development of Roger go to yellow three. They
were involved in presentations of the research at the 2011 Cambridge
Festival of Ideas and further interest in the project was reflected in its
discussion on BBC Radio 3's Music Matters programme and public
performances in Cambridge and Huddersfield, The performances of Roger
go to yellow three drew a further positive response from the
Wellcome Trust, who were impressed not only by the work's impact in
developing public understanding of the phenomenon of auditory streaming
but also by the way that the auditory tests embedded in the work enabled
the project's scientific advisers to undertake new scientific research.
The data collected in the Roger go to yellow three performances
was extensively analysed and yielded findings which offer new insights
into the phenomenon of masking. Dr Antje Heinrich presented an initial
survey of these findings, under the title `Stream segregation of speech in
live concert-hall performances of a 6-voice choir', at the British Society
of Audiology's 2012 conference.
The success of Roger go to yellow three, as a project which not
only encouraged public engagement in science but also enabled scientists
to gather new experimental data, led to the Wellcome Trust inviting The
Clerks to submit an application for a Large Arts Award to develop further
the work begun in Roger go to yellow three. Confirmation of the
impact of the research and the Wellcome Trust's commitment to the project
came in summer 2012 when this application was approved and the impact of
the project was further demonstrated by the widespread interest of
festivals and concert promoters in presenting the new work, Tales from
Babel. A fourth scientist, Dr Sarah Knight, joined the team to
oversee data collection and public presentations of the scientific aspects
of the project. Scenes from Tales from Babel were presented on 5th
April 2013 during the Second International Conference of the AHRC Research
Centre for Musical Performance as Creative Practice, at the British
Neuroscience Association's biennial meeting at the Barbican, London on 8
April 2013 and at Addenbroke's Hospital; the premiere of the complete work
was given as part of the Cheltenham Festival of Music on 7 July 2013, the
first date in a concert tour which extended into the autumn of 2013. In
the wake of the Cheltenham Festival there has been extensive media
coverage including BBC Radios 3 (In Tune and The Choir) and
5 Live, and articles in the Independent, NME, Times, London Evening
Standard and Guardian.
