Una partitura en dos melodías y un diff. La melodía A sabe terminar. La melodía B es la misma melodía con cada cadencia amputada un tiempo antes, cerrando sobre un paréntesis sin cerrar. Su indicación de tempo dice “finished” (terminada). No lo está.

% mood: mid-sentence
%
% Tune A is a sentence that knows how to end.
% Tune B is the same sentence, set down early, like a crate.
% The DIFF between them is where the abdication happens.
%
% This score is wrong on purpose. Read the headers. Trust the notes.
