Is it possible to create an open time signature bar in between existing bars of music?
I’m transposing an orchestral trumpet part and there is a bar in the middle where the cello soloist has a cadenza. Some of the notes in this cadenza, particularly the last few beats - trills, etc., will be cued in the trumpet part. I have created an open time signature for that bar after first making sure that the following bar had a “normal” time signature in place, but I have been unable to work out how to enter notes in that bar without them affecting the notation in the following bars. I have already entered all the trumpet notes and am going back to enter all the cues, which so far have stayed in the prevailing time signatures - no problems there. But this cadenza bar has me stumped.
I’m beginning to think that an open time signature bar needs to be the last bar of music - as you keep entering notes, the final barline just keeps on moving and making room for more until you enter a normal time signature. I have tried “normal” mode and Insert mode, but what I enter into the open time-sig bar either overwrites or moves the existing notation in the following bars.
I suppose another option is to work out how many beats I need for the cadenza and then create a sufficiently long time signature and hide it.
