Played organ sheet music on the piano and drafted Oldest Son to play the basso/pendals.

Anyway, we had great fun.
”Where am I?”
*offkey music*
”Oh it’s sharp?!” (both of us wincing)
”Hit the H!”
”What you mean H? Oh B?”

”After 2 years I finally learned G-A-B and now you call it an H?”
”Heads up on tempo, here comes the discant. Watch my right”
”I’m just learning to read notes and you’re making me read this?”
”It’s just single quarters. Easy peasy”
