Deconstructing the Rhythm Dot – The Mathematics of Dotted Notes

Updated on  August 9, 2018 to add an addendum on tupletting pairs of tied notes.

I recently needed to figure out ways to represent dotted notes so they would appear without a dot, and in the process, I found a number of ways to break down dotted notes into smaller notes. You may never need to do what I had to do, but someday one of these techniques may turn out to be useful.

String Numbers for Notes on Notation Staves in Sibelius

Some educational materials color or mark the strings on which notes appear for a stringed instrument. This document describes how string numbering can be used with plugins in Sibelius scores.

For notation staves there is no user indication as to which strings a note is assigned. Plugins can access string number for notes, but only if the notes had been copied to a Tablature (Tab) staff and copied back.

Curated Plug-in sets: Installing the first plug-in

A Curated Plug-in Set is a collection of Sibelius plug-ins that can be installed at one time and run from a single location. These sets are described in the Of Note post Working sets, My Plugins, and Curated plug-ins in Sibelius.

In order to install a curated plug-in set, you will first need to install the downloadable plug-in Install New Plugin, which will be used to install other plugins.

Here are step-by-step instructions for installing Install New Plugin. There are different instructions for Sibelius 6 and for Sibelius 7 or later.

Working sets, My Plugins, and Curated plug-ins in Sibelius

There are about 650 published Sibelius plug-ins, of which 150 ship with Sibelius. A lot of people never use plug-ins. They can’t find them, or can’t install downloadable plug-ins, or can’t figure out which plug-in does what. This is unfortunate, because plug-ins could save them a lot of work.

A Working Set of Plug-ins

In Sibelius, plug-ins are organized by category and you run them by finding their names on a menu or by using a keyboard shortcut.

As an alternative, you can create a set of favorite plug-ins that you identify by name and find in the same place. I call this a working set. The plug-ins in the working set should be ones you use often and will be easily available when you need them.

A curated plug-in set is a working set of plug-ins chosen for certain groups of users. It can be based on instruments, such as harp or guitar, or it can be created for a specific project or a school class. A set consists of a zip file containing a text file of plug-in names that make up the set and a folder of downloaded plug-in files which will be installed on your machine.

The files needed to create a curated plugin set can be provided by a plug-in curator, who is an experienced Sibelius user who selects a set of plug-ins that would be useful. This could be a teacher, or a co-worker, or anyone else you trust who is comfortable choosing plug-ins.

Plug-ins that run other plug-ins in Sibelius

Since Sibelius version 1, plug-ins have been able to run other plug-ins. For example, the Proof-read plug-in is just a container that lets you call the main Run() method of the plug-ins Check Pizzicatos, Check Clefs,… so you can do all your proofreading at once. These plug-ins were designed to be called by other plug-ins, and typically do not display a dialog when they run.


This document will discuss plug-ins that call the top-level Run() method of other plug-ins, which is equivalent to running the plugin from the plug-in menu.

Eliminating Duplicate Plugins in Sibelius


If you have multiple copies of a plugin in different locations (typically a downloadable plugin you have forgotten about installing, and so you installed it again to a different location), you may not be running the copy of the plugin you expect. This is true even if you explicitly run it from one of the plugin menus (or in Sibelius 6 and earlier, from the single plugin menu).

If the plugin files are identical it doesn’t matter which copy is run, but you may have installed an update which has different code, and you will find that you are not seeing the effects of the change.

Sibelius Plug-ins


What are plugins and how do I run them?

In Sibelius, plug-ins are extra features created using a programming language called ManuScript. Sibelius ships with about 150 plug-ins. These plug-ins are documented in the Sibelius Reference. Plug-ins can do many of the same things that built-in Sibelius commands do.
