Notes shorter than 1/4 usually get one or more flags depending on the note duration.
Short note duration notes can be grouped together under 1 beam
In MusiCAD these are called note clusters.
You can cluster individual notes (notated with flags) and put them under 1 beam with <,> or the button.
Decoupling or un-clustering in reverse is also possible and is done with <'> or the button.
MusiCAD performs clustering automatically using the time signature.
In a vocals part it is sometimes customary to write each note separately, regardless of its duration.
