Quote by Terry Pratchett
It wasn't that Nanny Ogg sang badly. It was just that she could hit notes which, when amplified by a tin bath half full of water, ceased to be sound and became some sort of invasive presence.

Summary
This quote from Terry Pratchett's Discworld series humorously describes Nanny Ogg's singing ability. The quote suggests that Nanny Ogg's voice is not on key, resulting in a cacophony of sounds that can be overpowering. The mention of amplifying her singing with a water-filled tin bath adds to the absurdity, implying that the sound becomes so disruptive that it turns into a disturbing and intrusive force rather than simple noise.
