Add Chord Notes Below Melody

Version 1.0
Added 11 Aug 2014 (last updated 17 Jun 2015)

For use with Sibelius 6, Sibelius 7.1, Sibelius 7.5 and Sibelius 8.x

This plug-in adds chord notes below a melodic line. It is designed to fill out a melodic line that already has an accompaniment.

To use it, select some notes and make sure some chord symbols are present in the same bars though not necessarily in the selected stave(s).

When run, the plug-in will add two or three chord notes below the melody line.

The “Stave containing the chords” option defaults to the lowest stave that has chords symbols. This can be altered here if desired.

The “Passing Notes” allows the user to double passing notes (non-chord melody notes) a 3rd or a 6th below. The best option depends on the musical context and some alterations to the plug-in’s output may have to be made.

With the “Omit Root” option the user can miss out the root from the added notes. This often sounds better in complicated chords and assumes that a bass part is present elsewhere.

Please note:
  • If a change of key-signature occurs in the middle of a bar then the doubled passing notes may be incorrect until the beginning of the next one.
  • Chord notes are only added to single notes. If a stem contains more than one notehead no chord notes are added.
