Before

Find your two hosts: one who can teach a melody with confidence and patience, and one who can play guitar or run a backing track. Music teachers, worship leaders, and that friend who always starts the singing at parties are all qualified.

Pick one song per night, and pick it for singability: something the whole room already knows, with a chorus that soars. Split it into three parts, low, middle, and high, and keep the arrangement simple enough to teach in 20 minutes. Print lyric sheets with the parts marked. No sheet music, ever; it scares off exactly the folks you want.

Book a bar's back room, a brewery, or a church hall on a slow weeknight, and set it up in Plurality with the song named in the invite. Charge nothing or next to it. Print your flyer in Plurality and share widely.

During

Warm up silly: a few stretches, one ridiculous vocal exercise, and everyone's laughing instead of nervous. Then divide the room by where folks are sitting, not by ability, and teach the lowest part first so the shy singers get anchored early.

Layer the parts and let it be a mess. The moment the three parts lock together for the first time is audibly magic, and it's what everyone came for, whether they knew it or not. Embrace every flub; the hosts' banter between takes is half the show.

Film one full take at the end, and tell the room that's the performance.

After

Share the video with everyone who came; it's the choir's trophy and next month's best invitation, and invite folks to record any other Moments.

Then invite folks to join the next session. Same room, new song, every month. Start a group in Plurality and make it a regular get together.

Then let the regulars take over the setlist. Members suggest songs, then champion them, then eventually teach them, and the night stops belonging to the hosts.
