What it does
An intelligent copy of a full measure is called a mirror; a measure composed of selected notes from several different measures is called a composite mirror. There may be times, however, when you want to display only selected notes from a mirror or composite mirror. For example, you might want a certain measure to display only a single monophonic musical line distilled from the chordal right-hand piano part from which it was mirrored.
For this purpose, Finale offers you the ability to choose individual notes from a mirror or composite mirror; the result is a selective mirror.
In this graphic window, you can click the handles of the notes you want to include in the selective mirror. You can pick individual notes out of a chord or, by drag-enclosing several handles, you can select groups of notes within chords. Finale will automatically provide rests to replace any notes you don’t select.
Click Prev and Next to scroll through other mirror measures. When you’re finished, click OK; Finale automatically enters the number of the selective mirror in the text box.
