+Ledger lines present a typographical challenge: they make it more
+difficult to space musical symbols close together and they must be clear
+enough to identify the pitch at a glance. In the example below, we see
+that ledger lines should be thicker than normal staff lines and that an
+expert engraver will shorten a ledger line to allow closer spacing with
+accidentals. We have included this feature in LilyPond's engraving.

 Musicians are usually more absorbed with performing than with

+Sheet music is performance material: everything is done to aid the
+musician in letting him perform better. Music often is far away from its

+traditionally printed sheet music always uses bold symbols, on heavy
+staff lines, and is printed on large sheets of paper. This "strong" look
+is also present in the horizontal spacing. To minimize the number of

 larger pieces with monotonous rhythms, spacing corrections lead to
 subtle variations in the layout of every line, giving each one a
 distinct visual signature.  Without this signature all lines would
