This dissertation presents composition project that includes a software tool and a
folio of scores and recordings. A composition method called Interval Restriction
Composition (IRC) is presented. The author has devised IRC for writing music
using the equal tempered chromatic, and the system comes under close
examination for its musical utility. A detailed study reveals that while IRC would
allow the composer to write music with a high degree of intervallic integrity, the
sheer volume of repetitive work needed to conform to the method places it out of
reach of a composer working without the aid of a computer. The field of
Computer Assisted Composition is then surveyed to determine whether available
composition tools are suitable for the automation of IRC. It is acknowledged that
there are tools that perform similar functions to that demanded of IRC, however
they are considered to be either inadequate or inappropriate. Consequently, a
software tool called Restricted Interval Counterpoint Engine (RICE) is presented.
RICE is custom designed to automate Interval Restriction Composition. RICE
also extends the system by providing musically useful functions, including
auditioning. A folio of RICE assisted compositions and recordings is presented.
These compositions are discussed in the context of RICE and IRC, as well as on
their own merits. This discussion includes an evaluation of the compositions and
the impact of RICE on IRC and the compositional process. Finally, discussion of
future directions for the technical and musical improvement of IRC and the
software conclude the dissertation.
