The HarmonySite App Essentials session, set for the evening of Thursday, August 27, 2026, is the kind of gathering that would have seemed almost absurd to those who founded what is now the global barbershop organization to which Lake Ontario Region 16 belongs. For the better part of a century, harmony was a matter of risers, sheet music, and well-worn learning tapes, not smartphones and QR codes. Yet here is a region that has spent decades singing four-part a cappella harmony suddenly convening its singers for a hands-on, evening class about app features, playlist creation, playback speed, and mobile tools. The meeting of those two worlds — the timeless craft and the thoroughly modern tool — is precisely the story.
The event itself is modest on paper. Billed as an educational offering, it starts at 7:00 p.m. on a summer Thursday, entirely virtual, open to members scattered across a sprawling territory. The presenter is Leila Brown, who has two roles: she is Region 16's Webmaster, and she is also the Musical Director of Barrie Soundwaves, a chorus based in Barrie, Ontario. Brown's dual role makes her a natural teacher for a hands-on session aimed at helping singers get more out of the HarmonySite app — from creating playlists and isolating one's own vocal part to adjusting playback speed, looping tricky passages, pulling up sheet music, and marking attendance with a QR code.
That Lake Ontario Region 16 needs such an event at all reflects the shape of the organisation that hosts it. The region is one of twenty-four SingUnited International regions that span the globe. It stretches across central and southern Ontario, Quebec, and into northern New York State, counting roughly eighteen choruses among its ranks. It is a cross-border institution in the truest sense, an entity that rehearses in both Ontario and Quebec, yet keeps its members linked by a shared repertoire, a shared competition season, and now a shared piece of software.
That software has roots that are, in their way, as charmingly homemade as the music itself. HarmonySite was created by a developer named Mark Virtue and has grown over the years into a platform used by singing groups around the world — choirs, choruses, orchestras, bands, clubs, and industry associations. The companion app is built by Northsoft Solutions and is free to download. For the app to work with a group's HarmonySite, the group pays an annual subscription, typically less than one dollar per member per year.
The app's feature list reads like a wish-list for a working singer on the go: push notifications, a music library, learning tracks that can be slowed to half speed or sped up to one and a half times, the ability to pan left and right to isolate a part, looping playback, and the capacity to play several tracks at once while viewing sheet music. There is an event calendar and a one-tap way to flag availability. Perhaps most novel, the app lets a member mark attendance simply by scanning a QR code the event coordinator has printed, a feature that exists only in the app, not on the website. There are also playlists, riser-stack arrangements, and a performance-readiness assessment tool that accepts recordings shared directly from a voice-recorder.
For the singers of Lake Ontario Region 16, such tools arrive at a moment of enormous change in their organisation's identity. For decades they knew themselves as Sweet Adelines, a community whose history begins with a group of women who gathered to test whether there was enough interest in women singing four-part barbershop harmony to form a society. The movement grew to spawn regions across the world, and Region 16 developed its own proud records, including the Toronto-based North Metro Chorus, which became an international chorus champion in 1997, 2000, and 2003. In 2026, the parent body, after generations as Sweet Adelines International, announced it would begin singing under a new public name: SingUnited International. The change was framed not as a break but as an evolution, a move to keep an inclusive, modern, global community relevant while preserving the mission of musical excellence and education at the heart of barbershop harmony.
That same spirit infuses a technical workshop on a Thursday night in late August. Barbershop, after all, has always been a form that travels across the divide between ear and page, passed from singer to singer through learning tracks and now through loops, panning, and playlists in a pocket. When Barrie Soundwaves captured its Division A Championship at the region's 2026 annual competition, the win came after members had spent months, in rehearsal and at home, drilling the arrangements that HarmonySite and its app were designed to put within easy reach. Leila Brown, the evening's host, is well placed to make the case: as musical director of that very chorus, she has lived both the musical and the administrative sides of the equation.
In the end, the HarmonySite App Essentials session is less about technology for its own sake than about belonging. A region stretching from Quebec to the north of New York can only rehearse the same song the same week if its members can carry a learning track in their pockets and swap notes online. The class is a modest little one, ninety minutes on a Thursday, but it represents something substantial: a women's harmony community, eight decades old, using every tool at its disposal to keep voices in tune and connected across an international border. The singers will still show up in person, on the risers, to ring the chords. But in late August, they will first tune their phones.
