Elaine Gould’s music notation reference Behind Bars has the following to say about dotted rests:
“Beats are more compact and thus easier to read when rests within a beat are combined.”
She recommends that dotted rests are used at the beginning but not at the end of the beat in simple time, but “it is acceptable to use dotted rests at both the beginning and the end of a beat,” though she says that the “visual difference between the types of rest is lost.”
“The longest permitted dotted rest,” Gould says, “is one value smaller than the beat. In crotchet [quarter note] metres, the longest dotted rest is a dotted quaver [eighth].”
Recently I had a passage in Finale in 3/4 time with a great many eighths and sixteenth rests (and vice versa) which I wanted to automatically combine into a dotted eighth rest. Of course, I only wished to combine those rest pairs which didn’t cross a beat, as indicated here:
The solution is far from obvious, but it can be done.
One key to the solution is buried within the MIDI/Audio menu. Select Quantization Settings… from the menu and click More Settings… to open another dialog box. Then check Allow Dotted Rests in Simple Meters. (If you have a passage in compound meter such as 6/8 or 9/8 that you want to fix, check Allow Dotted Rests in Compound Meters.)
Click OK twice to exit the dialogs. The other key to this riddle is to select your passage and head over to Utilities > Rebar > Rebar Music.
Like magic, the passage is transformed, just as intended:
It’s one of those great magical mysteries of Finale, where using MIDI and rebarring music tools had nothing to do with, uh, MIDI or rebarring music. But, I’m very glad it’s possible to accomplish this task, all the same!
