music = \relative b' {
  \time 3/4
  b4 b b | b2 \bar "||" \break
  
  % This adjustment to measurePosition is required to suppress
  % the warning "\time in mid-measure...."
  % 
  % The notation reference says,
  %
  %     \partial duration can also be written as:
  %       \set Timing.measurePosition -duration
  %
  % Assuming that the warning should remain because it is helpful
  % more often than not, can this workaround be improved upon?
  % I tried \partial 1*0, but it doesn't seem to be equivalent
  % as the notation reference would have me believe.
  \set Timing.measurePosition = #(ly:make-moment 0) % suppress warning
