| 13 | Cross-bar beaming | |
| 14 | </H2> | |
| 15 | <P> | |
| 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. | |
| 22 | You can then use the | |
| 23 | <A HREF="linecurv.html">line command</A> | |
| 24 | to fill in the gaps in the beams across the bar lines. | |
| 25 | </P> | |
| 26 | <P> | |
| 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. | |
| 31 | <BR><PRE> | |
| 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. | |
| 38 | 1: ms; | |
| 39 | invisbar | |
| 40 | ||
| 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.) | |
| 46 | score time=8/4n | |
| 47 | beamstyle=1/2 | |
| 48 | music | |
| 49 | ||
| 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. | |
| 59 | bar =b | |
| 60 | ||
| 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) | |
