On 19 May 1998, the Microsoft Corporation was granted a United States
patent (number 5,753,843) for a "System and Process for Composing
Musical Sections" (including 47 claims), this patent clearly pertaining
to the algorithmic generation of music. Computer Music Journal invited
Laurie Spiegel to write a guest editorial (below) about the implications
of such patents. We also invited letters to the editor in response to
the editorial.
The abstract of the Microsoft patent describes:
A system and process for comprising [sic] a musical section in response
to a user's interaction with a multimedia presentation. The system
includes a composition engine, performance engine, and arbitrator. The
arbitrator provides an interface with an application program running a
multimedia presentation. The arbitrator receives parameters from the
application program indicative of a user's interaction and the type of
music the application program requests in response to the interaction.
The parameters are passed to the composition engine which composes a
musical section having a chord progression and other data therein. The
musical section and a style provided by the arbitrator are used by the
performance engine to generate music sequence data for driving a musical
instrument. The performance of the musical sequence data by the musical
instrument occurs substantially contemporaneously with the user's
interaction which caused the musical section composition. Because the
composition engine uses processes which vary the composition of musical
sections, the user events which initiate composition of a musical
section and which occur at the same place within a multimedia
presentation, still vary the performance at each user event.
The claims includes the following text:
A system for composing music in response to a user's interaction with a
multimedia presentation comprising: an application program interface for
receiving parameters identifying a style, a shape, and a personality for
music that conform to said user's interaction with said multimedia
presentation; and a composition engine for composing a musical section
corresponding to said parameters so that a user perceives the
performance of the musical section to be related to said user's
interaction with said multimedia presentation."

Compositional Algorithms
Laurie Spiegel
There have been patents for musical inventions, such as piano action
parts, for many years without apparent detriment. However, throughout
the 20th century, the designing of artistic processes and creative
techniques has increasingly come to be considered an integral part of an
artist's creative work, rather than being seen as the province of a
separate tool-building specialist. Entire fields such as algorithmic
composition, interactive multimedia, and literary "process art" have
become established in recent decades, based on the premise that the
designing and implementation of specific creative processes and artistic
techniques constitute artistic creation, every bit as much as do the
data that such processes generate.
If specific compositional techniques are now to be privately owned, must
each composer, especially composers of computer-based interactive
process pieces, now stop to do patent searches routinely as part of
their work or else risk being taken to court? With the floodgates now
open for a gold rush of corporate claims to very specific compositional
techniques, how are we composers supposed to preserve our sense of
freedom, our exhilaration at exploring, and our deep psychological
immersion in following musical ideas wherever they may lead us, while
knowing that we cannot ever be sure anymore of the simple legality of
any new refinement we may make in our own process-based works?
Are we composers going to end up having to pay a royalty to the owner of
each technique we use, when the royalties we receive from the music we
compose using these techniques typically would not even pay for the
paperwork of just keeping track of them? Must the education of every
composer who wants to make process-based music now include courses in
what techniques are exclusively owned by whom and for how long, what
fees or methods will decriminalize their use, and the penalties to
expect for unauthorized use? Will process-based composing or composer
construction of interactive algorithmic tools now become so legally
complex (and possibly dangerous) that such approaches will simply die
out? When we want to use a specific compositional technique, how do we
keep the question of who owns it from interfering with our personal
sense of creative freedom?
As a method of motivating new development for compositional techniques,
how would the use of patents have worked in historical contexts? To
hypothesize an instance, what if someone had patented the replaying of a
musical theme at a time delay to itself, early in what was probably the
last great era of process-based composing: the era of Bach? Would Bach
have been able to afford, and also willing to pay, royalties (or--perish
the thought--legal defense fees) to use or build new techniques based on
the patented imitative contrapuntal processes his works required? Or
would composing the way he did have made him a criminal, as Galileo and
others came to be considered criminals for their scientific work? And
could any patent-holding tool designer ever possess sufficient
understanding of the working requirements of composers of Bach's
artistic caliber to be able to create procedural tools that were
adequately fine-tuned for every possible such composer's unique musical
approach? Or, in another hypothetical example, could any tool builder
whose products had been fine tuned for Haydn's methods have anticipated
the ways in which Beethoven would need to break out beyond their scope,
or why this would be important, or how to accommodate the change in
advance?
Then why does our own society assume that the definition,
implementation, and provision of any such creative technique should be
done non-competitively, non-pluralistically, under the complete control
of any single corporate monopoly? Why should the monopoly we call
"patent" include artistic methods, tools, or techniques within its
domain? Simply because these can now be constructed within the medium
of computer software, and because the law now allows the patenting of
such processes if implemented as computer software?
The only arguably successful scenario I can envision that takes as a
premise the existence of an 18th-century patent on time-delayed
repetition techniques, and that would still allow us the Well Tempered
Clavier, the Musical Offering, and the Art of the Fugue, is one in which
Bach got himself hired as Company X's official court (well, company)
composer, in a corporate reprise of the aristocratic private patronage
system. But in all likelihood Telemann would have gotten the job
instead.
We specialists created the field of computer music collectively but from
the intersections of our very own personal visions and desires. This
field, our lifework, is increasingly influenced by differently motivated
entities. The legal departments of large corporations, or those
concerned with the price of corporate shares trading in international
markets, might govern whether or not the next Art of the Fugue will ever
be made. The current situation is neither without precedent nor easily
resolved, but we do want to preserve what we value in our art and its
potential to evolve.
