16 Generally, beams do not cross bar lines, and Mup follows that rule.
17 However, if you want beams to cross a bar line, there are at least two
18 possible approaches to getting the
19 desired effect. The first is to explicitly specify
20 <A HREF=
"chrdattr.html#stemlen">stem lengths
</A>
21 such that all the beams in the various measures will lie on the same line.
23 <A HREF=
"linecurv.html">line command
</A>
24 to fill in the gaps in the beams across the bar lines.
27 The other approach is to draw in the bar line using the
"line
" construct.
28 To do this you first tell Mup that a measure is twice as long as is really
29 is, so that you can put two actual measures inside what Mup thinks is a
30 single measure. Here is an example.
32 // First make an empty measure ending with an
33 // invisible bar. This is for the sole purpose
34 // of allowing the real time signature to be
35 // printed and would not be necessary if we
36 // wanted to cross a bar line other than
37 // the very first bar line of the piece.
41 // Now, make the effective time signature twice
42 // as long as the real time signature, but use 'n' so this fake
43 // time signature is not actually printed.
44 // Set up for beaming across the entire double-length measure.
45 // (You could could use other beamstyles if you wish, or custom beaming.)
50 // Now do the double-length measure. On the chord
51 // just after where we want a bar line, add some extra
52 // padding and set a location tag so that we can draw
53 // a bar line relative to the tag.
54 1:
8c;e;f;d;g;e;f;a; [pad
3; =a]g;e;f;a;g;d+;
4c+;
55 // Also set a location tag on the next bar line,
56 // so that we can get the vertical endpoints of the
57 // bar line that we draw from the endpoints of the
58 // normal Mup-supplied bar line.
61 // Now draw the bar line that goes through the beam.
62 // Use the horizontal position relative to the
"a
"
63 // location tag on the chord in the second actual measure,
64 // and get the vertical endpoints from the
"b
" tag
65 // associated with the next bar line.
66 line (a.w +
1, b.y +
4) to (a.w +
1, b.y -
4)
