It is not uncommon for the appearance of
a time signature to differ between the score and parts. For example, a
single large time signature may be used for several score staves. And
of course, a single time signature is required for each part. To accommodate
this, Finale allows separate document settings for time signatures -
one set for the score and one set for parts in Document Options - Time Signatures.
You can use Staff Styles to apply a different
instrument transposition, clef, or other staff attribute to a part. See
To display a staff
differently in one part than another.
