| 16 | The "invisbar" can be used | |
| 17 | to force Mup into | |
| 18 | doing something in the middle of a bar that it normally would allow | |
| 19 | to happen only at a bar line. | |
| 20 | Suppose, for example, you wish to place a | |
| 21 | <A HREF="bars.html#reh">rehearsal letter</A> | |
| 22 | in the middle of a measure. This could be accomplished as follows: | |
| 23 | <BR><PRE> | |
| 24 | // assume we are in 4/4 time, but want | |
| 25 | // a rehearsal letter by count 3 | |
| 26 | // of the measure | |
| 27 | ||
| 28 | // do first part of measure and use "space" | |
| 29 | // for last part so time values will add up | |
| 30 | // properly to a full measure | |
| 31 | 1: 4c;d;2s; | |
| 32 | ||
| 33 | // put in invisible bar with rehearsal letter | |
| 34 | invisbar rehearsal let | |
| 35 | ||
| 36 | // now do the last half of the measure, | |
| 37 | // this time with space at the beginning | |
| 38 | 1: 2s;4e;c; | |
| 39 | bar | |

| 44 | As another example of invisbar use, suppose you want to add a "courtesy" | |
| 45 | key signature at the end of a repeated section to remind the player that the | |
| 46 | beginning of the repeated section is in a different key. This can be done | |
| 47 | by adding an empty measure whose sole purpose is to produce this key signature. | |
| 48 | <BR><PRE> | |
| 49 | score key=3& | |

| 51 | 1: g;f;e;d; | |
| 52 | repeatstart | |
| 53 | 1: c;e;f;g; | |
| 54 | dblbar | |
| 55 | score key=0& | |
| 56 | music | |
| 57 | 1: g;f;e;d; | |
| 58 | bar ending "1." | |
| 59 | 1: f;e;2c; | |
| 60 | // add a courtesy key signature, | |
| 61 | // to remind player the beginning | |
| 62 | // of the repeated section is in | |
| 63 | // a different key | |
| 64 | invisbar | |
| 65 | score key=3& | |
| 66 | music | |
| 67 | 1: ms; | |
| 68 | repeatend ending "2." | |
| 69 | 1: e;d;2c; | |

| 75 | You can use a similar technique to insert time signatures, clefs, etc. | |
| 76 | at unusual places. | |
