Hans Sangtoki

Hans Sangtoki is an Indonesian-Australian conductor and founder of Horizon Orchestral Studio. He is currently the inaugural Honours in Conducting candidate at the Sydney Conservatorium of Music, studying with Professor Benjamin Northey.

Hailed as "a disciplined leader and an expressive, emotional conduit" who conducts with "an unanimity of purpose and expression" (Sounds Like Sydney), Hans led the Horizon Orchestral Studio in performances of Symphony No. 6 'Le matin' and Copland's Appalachian Spring in the debut presentation of Horizon Classical — a new concert platform Hans has founded to rethink how conductors are trained and how classical music is experienced.

Hans has participated in masterclasses with the Tasmanian Symphony Orchestra, Jakarta Simfonia Orchestra, and The Orchestra Project. He has undertaken private study with conductors Alexander Briger, Natalie Murray Beale, Brett Weymark OAM, and masterclasses with Rebecca Tong and Fabian Russell amongst many more. In June 2026, he heads to Bandung Philharmonic's Orchestral Academy for a masterclass with French conductor, Maxime Pitois.

Hans has a vast musical background training in piano and collaborative piano at the Sydney Conservatorium of Music with Natalia Ricci, Theresa Leung and Eun-Jung Byun. Hans has performed as a chamber musician with Alexandra Osborne and Simon Lobelson. He has worked extensively with singers playing in the studios of Maree Ryan AM, Anke Ryan-Hoeppner, and Russell Harcourt. He has also studied continuo and harpsichord with Prof. Neal Peres Da Costa, and performed continuo for SCM's production of Monteverdi/Elena-Kats Chernin's Coronation of Poppea.

As a church musician, Hans is the artistic director and co-founder of Cantate Deo Youth Orchestra, the resident orchestra of the International (Indonesian) Reformed Evangelical Church (IREC) in Sydney. In 2025, Hans directed the orchestra alongside the Soli Deo choir, resident choir of IREC, in Handel's Messiah — the first performance of its kind amongst the Indonesian diaspora in Australia.

Aside from ministerial work and developing new appreciation for sacred music, Hans along with Cantate Deo Youth Orchestra is committed to opening classical music to new audiences through regular education and outreach concerts which aim to introduce many young audiences to the orchestra and instil an early passion for classical music.

As musician and founder, Hans' work is based upon a fundamental belief that music and musicians play a vital role in broader society to reflect, sustain and create culture, and that a wholistic integration from industry, craft to artists is needed for music to continue to flourish into the future.
