Margo Schulter has been interested in European medieval, Renaissance, and Manneristic music since 1966; in 1998, John Chalmers of Xenharmonikon invited her to join the Alternate Tuning List, she saw Xenharmonikon 17, and was fascinated by what she read. In 2001-2002, she had the precious opportunity to collaborate with George Secor in an exploration of his 17-tone well-temperament of 1978; this process led her to explore Near Eastern music, as well as isoharmonic sonorities and Kathleen Schlesinger's superparticular melodic series. Jacky Ligon was a vital formative influence, and later Ozan Yarman and Jacques Dudon and Stephen Pohlit. She lives in Sacramento, California.

Dylan Crismani is an Australian composer, instrument maker, and lecturer in music at The University of Adelaide. Dylan's compositional style aims to fuse American minimalism with European spectralism and microtonality.

Paul Johnson (b. 1997) studied composition with David Vayo and Kyle Shaw, and has composed chamber pieces based on large-scale processes structured improvisation, and game rules. He holds a degree in mathematics and physics from Illinois Wesleyan University, and is interested in Erv Wilson's combinatorial and graph theoretic approaches toward tuning spaces. He is currently pursuing instrument building, and wants to use Harry Partch's "Corporiality" as a unifying concept for both popular and spectral composition.

Praveen S. Venkataramana considers himself a Wilsonian in approach and has composed a variety of chamber, solo, and electronic pieces in various tuning systems. He is mostly self-taught in music but he studied cello with Rich Eckert, South Indian music with Neyveli Santhanagopalan and composition with Keeril Makan. He received a Philip Loew Memorial Award for creative accomplishment at MIT and his music has been performed by the ensembles Either/Or and Sound Icon.

Born in New Zealand in 1961 Michael learnt piano with his grandmother, horn and composition with his father. Composition is a significant part of his musical life, having written for a variety of ensembles along with songs and percussion works. A considerable number of his compositions include intervals from the harmonic series, extended just intonation. His music is published by Wirripang Pty Ltd ( From 2017 he has been co-curating SydneyMicroFest, an annual event of microtonal music. He has a blog exploring brass instruments, harmonics and just intonation, ( and a composition service
Micahel has held full-time playing positions with a number of Australian orchestras including that of Principal Horn in the Queensland Philharmonic Orchestra. He is now a regular with the Australian Brandenburg Orchestra (playing natural horn), Opera Australia Orchestra and freelances mostly in Sydney. Chamber music credits include his ensemble LOCANA and Omega Ensemble.
Teaching is an important part of Michael's work with schools in Sydney including Inaburra School. In 2011 he was awarded the degree of Doctor of Creative Arts from the University of Wollongong after having previously been awarded an MPhil in composition from the University of Queensland and MMus in Musicology from Griffith University.

Marcus Hobbs is a software developer focused on both creating software tools and using them to create visual and musical art. His first career was at Walt Disney Feature Animation whereas a digital artist he developed software used to create 3D artwork for Lion King, Pocahontas, Hercules, Atlantis, and Mickey’s Philharmagic, and Meet the Robinsons. He is currently developing mobile application software synthesizers that support microtonality, particularly focused on implementing the works of musical scale designer Erv Wilson. His iPhone and iPad application “Wilsonic” implements many of Wilson’s scale designs with interactive parameters so that musicians and composers can customize these designs to suit their values. He is a developer of “AudioKit Synth One”, a free open source additive software synthesizer which can import scales designed in Wilsonic.

Warren Burt (b. 1949) is a composer, performer, instrument builder (both
acoustic and electronic), sound poet, video maker, writer and educator. Originally from the USA (he studied in Albany NY with Joel Chadabe and in
San Diego with Robert Erickson and Kenneth Gaburo), he moved to Australia in 1975 and has mostly been based around Melbourne ever since.
His PhD (2007 University of Wollongong) is a survey of 35 years of microtonal composing activity. He is currently (2019) Coordinator of Master’s Programs in Music at Box Hill Institute, Melbourne.

Canadian composer of Ukrainian descent Marc Sabat (*1965) has been based in Berlin since 1999. He makes pieces for concert and installation settings, drawing inspiration from investigations of the sounding and perception of Just Intonation and of various music forms — folk, experimental and classical. He is a frequent collaborator, seeking fruitful interactions with other musicians and artists of visual and literary modes to find points of shared exploration and dialogue between various forms of experience and different cultural traditions.
