Imagine a 3/4 bar with three quarter notes in it. I want to change this to a 4/4 bar and change the first note to a half note. How do I do this?
If you want to return to 3/4 at the start of the next bar, first re-input another 3/4 time signature at the start of the next bar.
Then, activate Insert mode (press I) and input a 4/4 time signature at the start of the bar. Then with Insert mode still active, lengthen the first note - Insert mode means everything else after that note in that voice gets pushed back accordingly. Deactivate Insert mode when you’re done.
If you don’t want to show the time signature, you can hide it afterwards. You can also just insert a beat’s worth of time into the existing bar without adding time signatures, but I personally wouldn’t recommend that if you’re going to give this music to real people to read
Thank you. I would not have thought of doing it that way.
