Everyone Can Code
Coding opens up a wealth of possibilities for exploring
new kinds of musical structures and ideas
OMN is designed as a scripting language for musical events. It’s not about sounds themselves, it is about their control and organisation in a musical composition. As a linear script rather than a graphic stave, musical events can be transformed, extended, reorganised by powerful computer algorithms. Some sequencers and score writers provide basic algorithms, but they do not represent the way composers now think about the process of music composition. Composing has become such a multi-faceted process and takes ideas about structure and content from many disciplines: mathematics, astronomy, literature, the visual arts. As such it requires extensive mental resources and experience from the composer. Much of this is still done by hand and eye and brain because although computer systems do exist to help the process along they don’t provide what has become known as the composing continuum.

Microtonality
Microtonal music or microtonality is the use in music of microtones—intervals smaller than a semitone, also called "microintervals". It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave. In other words, a microtone may be thought of as a note that falls between the keys of a piano tuned in equal temperament.
Luigi Nono, Fragmente-Stille, An Diotima, Violin 1 (fragement, 1979-1980)
Tonnetz
In musical tuning and harmony, the Tonnetz (German: tone-network) is a conceptual lattice diagram representing tonal space (net) first described by Leonhard Euler in 1739. Various visual representations of the Tonnetz can be used to show traditional harmonic relationships in European classical music.
In Opusmodus there are 12 Tonnetz structures labelled by a number and by an intervallic content of the composite chord. The intervallic content is a number of semitones associated with the different interval axis.

Counterpoint
In Opusmodus the COUNTERPOINT function designates patterns to a number of voices with defined methods for each voice.

Micropolyphony
Micropolyphony is a polyphonic musical texture developed by György Ligeti which consists of many lines of dense canons moving at different tempos or rhythms, thus resulting in tone clusters vertically. According to David Cope, "micropolyphony resembles cluster chords, but differs in its use of moving rather than static lines"; it is "a simultaneity of different lines, rhythms, and timbres".

Graphs
Making 2-D visualisations of musical parameters offer a new way of conceptualisation. Opusmodus graphical tools can plot pitch, rhythms, duration, dynamics and orchestration and there's a host of different display paradigms available. The composer can now view the interaction of multiple streams of parametric data, a perfect way to take in complex algorithmically-generated material. Composers often use such visualisations in the early stages of a project before precise pitches or rhythms are decided upon.
Composer Workshop
with Stéphane Boussuge
Courses and private lessons to students and professionals interested in composing music with Opusmodus. Composer Workshop provide lessons for beginners and advanced users with or without programming knowledge, online or on site.
Fundamentals of composition
with Opusmodus
Marco Giommoni – Janusz Podrazik
This is the first volume of a series of publications specifically dedicated to composition and analysis of music using the Opusmodus system. This volume focuses on the basic elements of the system and on the “fundamental" strategies in defining symbolic expressions in a text-code i.e. generation and transformation of musical material to create a score. In this book, a few pages were dedicated to the history of musical theory, with particular reference to the relationship between numbers and music in the second half of the 20th century. The purpose of the book is therefore to demonstrate that the use of Opusmodus system is simple, linear, easy to learn and within the reach of every musician, and is by no means part of a universe reserved only for the few.

Testimonial
Opusmodus is currently the most advanced software for computer-assisted composition available. It comes with the highest development potential to fulfil the aesthetical and technical requirements for contemporary composers. At the University Mozarteum, Salzburg Opusmodus is already part of the compositional education and will be the preferred production environment in the future.
