Encoding notes without stems in a measure - free measures
To create a free measure with notes without
stems, you can disable automatic justification (except with
Pizzicato Light) and freely place whole notes in the measure.
With Pizzicato Professional and Notation versions, you can then
change all the note heads in a quarter note head or another
symbol (by selecting the measure and going in the "Change
the notes head" item of the "Edit" menu). With the
Beginner version, you can use quarter notes and reduce the stem
height to zero. Pizzicato Professional (and some other versions)
also lets you create free measures. Select the measures and in
the Measures parameters item ("Edit" menu), check the
"Measure duration" check box and select "Free on
the basis of a" with the value of a quarter note, for
example. By keeping the automatic justification, Pizzicato will
align the notes correctly and you will be able to listen to the
result according to the number of beats present in the measure.
