A Glimpse into a Composer’s Workshop
• CAC systems focus on the formal structure of music.
• We conceive a CAC environment as a programming language, enabling composers to constitute their personal universe.

Pre-Composition
Eckhart Richter’s ‘A Glimpse into the Workshop of Paul Hindemith’ (Richter 1977:122) describes Hindemith’s working method as presented to a class at Yale in 1951.
1. The general determination of the character, medium and the basic purpose of the piece, as well as its expressive character, and even place of performance
2. A master plan of formal design, including the overall shape, the number and character of sections, changes in mode and tempo, rhythmic character, texture and the degree of activity . .
3. Then ‘came the tonal layout in which the basic tonalities of each section and their relative degrees of tonal stability and complexity, as well as the modulations, were mapped by means
of a diagram’.
4. Specific thematic material.

The Hierarchy of Action
A musical composition tends to display a hierarchy in the arrangement of parametric elements.
Bach's Prelude in C from WTK could be said to have this hierarchy:
Harmony
Harmonic Rhythm
Note-length
Pitch
Rhythm
CAC needs to allow the composing process to start from any parametric element.
Index
Traditional Practice
The need for a composer to really understand the elements commonly used in his/her composing.
"The problems of language, meaning, and form must remain central to the composer, and he has constantly to set himself up against the history of his own art."
Alexander Goehr in Finding the Key (1998)
This book contains some valuable descriptions of the composer’s own pre-composition processes and that of his teachers Richard Hall and Olivier Messiaen.
Index
The Experience of the Ear and Eye
•Experience based on studies of existing scores and practice.
•What works well with performers - in slow/fast tempos?
•How are changing metres presented? (with time-signatures or the use of accents)
•The value of visual scanning to the process of building a musical structure of many parts and sections.
Index
Internalisation
How important is the ability to hear in one's imagination the detailed sound of the music as it develops?
Is the intervention of computer-assisted playback of musical elements helpful or a hindrance?
Are we only experiencing the outer layer of the musical message?
Index
Meta-composition
Index
Can we think about composition as a play of symbolic elements?
Can we work 'back to the notes' from speculative symbolic ideas?
Hindemith favoured a process of thinking about composition in which 'the notes' assumed the lowest position in the hierarchy of planning a musical work.

Generative Techniques
What are the basic / essential generative techniques composers use during the pre-composition stage?
Can these techniques be defined as functions able to act on individual parametric elements?
What other techniques do we need to have available to enable 'good continuation' ?
How important is analysis in defining generative techniques?
Are we talking about reverse engineering?

The Notated Score & Summary
What are the mechanisms that enable the rendering of pre-compositional material into a notated performance score?
What are the expectations?
What are the common difficulties and anomalies?
Summary - The Composing Continuum
• In the making of music for human performance a small, but significant number of composers use Computer Assisted Composition.
• Very few of these composers a) have sustained a long-term association with a CAC or b) acknowledge how and to what degree compositions are made with computer assistance.
• Informal and anecdotal evidence suggests that a) it is rare for a composer to even attempt the composing continuum (pre-composition to notated score), b) most use the CAC to generate unique material in one parametric element only - usually pitch.
• There remain unresolved issues in the translation from midifile (the favoured output of most CACs) to staff notation: time-signatures and metre zones (bars), tuplets or irrationals rhythmics, metrical modulations, microtones, articulations.

The Fall
It is the fall, the eternal fall of water,of rock, of wounded birds, and the wounded heart,the waterfall of freedom. Angels falllike lovers from the azure, separate,and die by that same death that ends us all.
Falling ten million years, we fling ourselvesagain into the inviting arms of time;our nuptial flight must end again in deaththat serves for freedom time and time againwhile the hard labouring mystic holds his breath.
The watching surface of the living seaever intact, smiles with the face of love,where living blood drowns in its ecstasy,impelled by nature that can mountains move,feeling most freedom when it least is free.
Shall we go down, shall we go down together?here on the mountain top, the wind and snowurge us to fall, and go the way they go.The way is clear, the end we shall not know,the sea will carry us where tides run and currents flow.

The Effect of Digital Technology on Musical Creativity
What has digital technology to offer the composer searching for the right note, the appropriate chord, the smooth transition from one idea to another? Are the current tools and systems, said to
make us more creative and productive, delivering the goods? Or, are there intrinsic problems that may be already having a serious
effect on the development of composers whose formative relationship with music composition has depended on interactions
with technology? To this end, the paper considers a study of undergraduate students working with computer sequencers and
describes research and development of new tools for music composition and its teaching and learning. It concludes with
recommendations that suggest composers empower themselves to take control of digital technology, rather than being controlled
by it; to move away from the emphasis on production and performance outcomes towards the development of personal
environments responsive to creative and critical thinking.

Teaching Cycles in the Creative Community of Inquiry
Nigel Morgan and John Cook
In this paper, five studies are described which investigated the way in which tutors (both human and computer-based) were used to support a ‘creative community of inquiry’ in undergraduate musical composition. Each study involved a cycle around some or all of the following four elements
• dialogue analysis
• learning support system design
• implementation of a learning support system
• evaluation of the system plus reflection on the
implications for music composition teaching
The paper concludes with a reflection on the impact that this cyclical research and development has had on the practice of a composer-teacher (the first author).

Composing: How and Why
Index
John Cook and Nigel Morgan are currently working on a book titled:
Composing: How and Why
Technology offers the promise of reinstating composing once more at the heart of musicianship. Just as visual arts practice and creative writing have been demystified by photography, the word processor and the internet, the complex skills and techniques surrounding music making are being redefined and made newly accessible by digital recording, interactive machine musicianship and synthesis. In the light of these new conditions revisiting and reinventing traditional forms of learning and thinking about music can offer us a lively way forward to developing the creative and critical tools to make and understand new music. The authors believe that interactive portals able to foster creative and critical thinking will soon be a part of new technologies that are responsive to an individual’s learning needs: to encourage self-explanation, speculation, and reflection about intention. We can even look forward to the machine becoming a kind of knowledge-mentor prompting us to explain our intentions, formulate our plans, recognise areas of weakness and review outcomes as part of the creative process.
Composing: How and Why
Index
Composing: How and Why examines the relationship of thinking to composing and how dialogue and self-explanation can mediate between listening and making one's own music. It examines how musical learning has traditionally employed modes of thinking and questioning and how these today might be remodeled and embedded within the technologies and media through which we will increasingly learn and gather information.

Index
Many contemporary scores offer few clues to their pre-compositional activity and their ‘making’ process.
Much new music requires in its execution a high degree of technical precision leaving very little interpretative space for a performer to bring his/her experience to bear on the music.
An effective
Pre-Composition- Audition/Simulation - Notation Continuum offers possibilities for musicians to gain access to the content

The MPEG Ad Hoc Group on Symbolic Music Representation
Created by MPEG the basis of the request of members of the MUSICNETWORK which is a large network in which are present more
than 850 participants and more than 400 institutions and companies.
Maxwell and Ornstein’s groundbreaking Mockingbird music editor pioneered the approach of storing independently information about the logical, performance (also called gestural), and graphic aspects of music. NIFF, as well as Nightingale and other programs, adopted
that approach; SMDL added a fourth “domain,” for analytic
information. We strongly advocate this independent-domain model.
