Full Idea
The most miserable performance without actual mistakes does count as an instance of a work, …but the most brilliant performance with a single wrong note does not.
Gist of Idea
A performance is only an instance of a work if there is not a single error

A Reaction
Mereological essentialism applied to art! You need to be a highly theoretical and technical philosopher (which Goodman was) to maintain such a weird and contrary-usage proposal.
