A pitch is a float number representing the height of the note. the musical object note names ParamĬonst major = scaleGen ( ) const Cmajor = major ( 60 ) Cmajor ( 0 ) // => 60 Cmajor ( 1 ) // => 62Ĭreates a pitch.

Catalogs of all scales used in the thesis, as well as Scala files for all scales, and all data used in composing the pieces is also contained in the Appendix. Recordings of all compositions discussed are contained in the electronic Appendix, on the attached DVD-Rom. This thesis discusses how these tunings, algorithms, real-time processes, instruments, and collaborative relationships were used in creating these compositions. Investigation into the role of timbre and tuning in sonification was carried out with the help of the Wollongong Room Calorimeter project, led by Professor Arthur Jenkins. ![]() Software instruments designed to perform the algorithms used were developed in collaboration with John Dunn of Algorithmic Arts, in Fort Worth, Texas. ![]() Other works used electronic timbres designed to explore placing of sound in space produced by the interaction of timbre, tuning and room acoustics. Acoustic instruments were built or adapted to perform some of these works, including microtonal plucked-string and percussion instruments, and the computer-controlled microtonal instruments of Godfried Willem Raes at the Logos Foundation, in Gent, Belgium. The desire to compose works of extended duration was aided by the large size of some of these scale families, which consist of between 60 and 276 new scales each. Wilson’s ideas, such as Moments of Symmetry (MOS) scales, Euler-Fokker Genera, limit-ratios, the Scale Tree, and additive sequences and their derivation from number triangles, as well as other tuning ideas, such as permutations of the materials of the ancient Greek modal system were all extended and developed into families of interrelated microtonal scales. Some of these works involved collaborative relationships with other musicians, hardware and software instrument designers, and scientists. Tuning ideas developed by Wilson and others were extended and expanded into several families of new microtonal musical scales, which were used as the basis for composing a series of algorithmic real-time musical works of extended duration. Encountering his work spurred me on to further investigations in sound and tuning, in a series of compositions using electronic, acoustic, and robotic acoustic instruments. Following a lifetime of creative work and investigation into algorithmic composition and microtonality, I became interested in the speculative mathematical music theory of Ervin Wilson.
