#(set-global-staff-size 24)

% This creates a simple grid of single measure/two staff scores (mini scores). The 'mini scores' are used within a
% \markup construct. Then by creating an 'invisible system' as a 'frame' and attaching these 'mini scores' as
% \markups to notes within the 'invisible system' it is possible to create the grid effect.
% The single 'mini score' on its own in the first line is just to show one on its own.
% By adjusting the global-staff-size and the X offset of the mini-score contruction (below) it is possible to create more or less mini-scores per line.

\paper {
  % Indent of 0\mm required to make first markup align with the measure below as without it
  % the first measure of the invisible score is indented and throws off the alignment of the first
  % mini score
  indent = 0\mm
  % This just spaces out the 'grid' evenly, top-to-bottom
  ragged-last-bottom = ##f
  % uncomment this line to remove the default LilyPond tag at the bottom of the page
  % tagline = #ff
}

  % 'musicall' is the name of the 'invisible score + \markups of the 'mini scores'' used in the final \score
  % construct at the end of the file

  % \textlengthOn is required to keep the horizontal spacing consistent else the 'mini scores' will collide
  % or touch each other.
