There are two kinds of slashes, or hash marks, used to indicate improvised chording or comping. If you want to indicate ad lib comping, but you don’t require a specific rhythm, you can let Finale fill the measures with stemless slashes, spaced according to the time signature (four slashes in a measure, for example, at right in the figure below). If you want to indicate a specific rhythm of comping, Finale can turn the noteheads of any passage into slashes, still beamed and stemmed (at left in the figure below).
You can also create a passage of mixed normal notation and slash notation, and you can also turn any individual notehead into a slash. See Guitar Notation.
To create ‘comping’ slashes
To add chords above slash notation, first add notes or rests in the staff, attach the desired chord symbols, and then apply the Slash Notation staff style to the region. For more information regarding adding chords without notes, see To enter a chord symbol when there’s no note below it. Note you can also create slash notation using the Rhythm Generator Plug-in.
