I'm guessing here, on how I would try to accomplish this....

I do not believe BB will allow partial measures from what I have seen so you will need to use a workaround.

In the intro, select a 2 bar intro and insert a chord in the first measure followed by 3 dots. I believe that is a silent chord.

You can also enter a chord into the second half of the measure for beats 3 & 4.

In addition, if you enter G, D into the 2nd chord window in the measure it will play the G on the 3rd beat and D on the 4th....

I use this quite often to "walk the chords" or the bass line (G/G#, G/A) so...while I have never tried this>>> placing 3 dots G...,A for example, might let you start the tune on the 2nd or 4th beat in the measure rather than the first or third.

There are all sorts of cool workaround things .... for example you can also mute just specific instruments in measures.... In a song I'm working on now, I have a few measures where the band stops but the drums continue to play.....also in the intro it's just a drum beat.....

I have found that if I can think it, I can normally get BB to do it in some fashion.

You can make excuses or you can make progress but not both.

The magic you are looking for is in the work you are avoiding.
