% The marking should start at "\staffHighlight".

% If there is a full-bar rest and a tempo marking in the first bar, 
% the marking starts at the end of the tempo marking and ends at 
% "\stopStaffHighlight". If there is a long tempo marking, the 
% marking starts at "\stopStaffHighlight" and ends at the end of the 
% tempo marking.

% If there is a full rest instead of a full-bar rest, or if there are 
% notes, the marking starts at "\staffHighlight". The same applies if 
% there is no tempo marking.
