I have a song I'm working on where the chorus ends with a half note in the first half of a measure. I would like to do an instrumental/solo, I want to allow freedom to the musician so I have just filled the measure with beat "slashes". My question is if a measure already contain musical notation in the first half, should I use two slashes instead of a rest in the second half of the measure or wait until the next measure to start the slashes? Should I do it like this:
I tend to prefer the second as I want the soloist to do a pickup into the second measure. But I've been told I should not mix standard notation with slashes in the same measure. Any thoughts or advice?
