Our Service Approach

Middle C. Pianos approaches every appointment with an open mind and a positive outlook. After 15 years of tuning in Toronto, Andrew has espoused an all encompassing (holistic?) approach to piano service that seeks to achieve the most stable results for your piano, no matter the age or make. This means consulting on everything from humidity control to room acoustics as part of a normal tuning.After 28 years of combined piano tuning and rebuilding experience work formerly with business AND marriage partner, Sarah Davignon, for nearly all Toronto piano dealers and rebuilding shops, Andrew Patten now runs his own professional piano tuning and repair service. (Sarah’s too busy making ice-cream!) Whether you’re seeking the highest possible performance from your new instrument, or simply wanting to get playing on an old Toronto-made Heintzman, we’ve seen it all, and can manage anything your piano can throw at us.

In 2008 Sarah C. and Andrew C. trained at UWO’s piano technology program & extended rebuilding semester.
Sarah then interned for the Royal Conservatory of Music’s tuning department and Andrew began a junior position tuning pianos with Robert Lowry’s piano experts, Toronto’s last large-scale piano restoration space.
From 2009 to 2014, Steve Jackson Pianos afforded them the unique opportunity to conduct comprehensive piano restoration and repair work on rare, historical instruments. They completed several piano rebuilding projects and, on their own, rebuilt a lovely Mason and Hamlin model A for their own private use.

In 2017, they trained in voicing and regulation at the Bechstein Academy in Germany. Andrew honed his piano voicing capabilities while Sarah trained in the factory's action department.By 2022, Andrew left his senior technician position at Merriam Music in order to focus entirely on building the Middle C. Pianos name into an agile and professional piano tuning and repair company able to serve Toronto and the GTA quickly and reliably. Sarah has gone on to run an ice-cream chop called [moonmilk] (https://moonmilktoronto.com), but Andrew still borrows her tuning tools from time to time.
