The space taken by a note is determined by the formula
-arithmetic_multiplier * ( c + log2 (time) ))
+ SPACE = arithmetic_multiplier * ( C + log2 (TIME) ))
+
+where TIME is the amount of time a note occupies. The value of C is
+chosen such that the smallest space within a measure is
+arithmetic_basicspace:
+
+ C = arithmetic_basicspace - log2 (mininum (SHORTEST, 1/8))
+
+The smallest space is the one following the shortest note in the
+measure, or the space following a hypothetical 1/8 note. Typically
+arithmetic_basicspace is set to a value so that the shortest note
+takes about two noteheads of space (ie, is followed by a notehead of
+space):
+
+ 2*quartwidth = arithmetic_multiplier * ( C + log2 (SHORTEST) ))
+
+ { using: C = arithmetic_basicspace - log2 (mininum (SHORTEST, 1/8)) }
+ { assuming: SHORTEST <= 1/8 }
+
+ = arithmetic_multiplier *
+ ( arithmetic_basicspace - log2 (SHORTEST) + log2 (SHORTEST) )
+
+ = arithmetic_multiplier * arithmetic_basicspace
+
+ { choose: arithmetic_multiplier = 1.0*quartwidth (why?)}
+
+ = quartwidth * arithmetic_basicspace
+
+ =>
+
+ arithmetic_basicspace = 2/1 = 2
+
+If you want to space your music wider, use something like:
+
+ arithmetic_basicspace = 4.;
-where code(time) is the amount of time a note occupies. The value
-of code(c) is chosen such that the smallest space within a measure is
-arithmetic_basicspace. The smallest space is the one following the
-shortest note in the measure. Typically arithmetic_basicspace is set
-to the width of a quarter note head.
