What is it?
The point at which a neume, usually a complex one, is divided into smaller, separate components.
The same neume, like a pes subbipunctis, can be visually expressed in a variety of different ways. These differences determine which note(s) receive emphasis. The note(s) following a break receive emphasis. If no break is present, then the neume is entirely light and fluid.
Default pes subbipunctis
Entirely fluid, no break – “corsiva”
Modified pes subbipunctis
Neumatic break after initial tractulus – “non corsiva”
Why did scribes depict the neumatic break?
Highlight modally-important note(s)
Note(s) after the neumatic break may be structurally important.
Provide repose in melismatic formulae
Note(s) before the neumatic break may give time for singer to breathe.
Emphasize melodic idea
Note(s) before & after the neumatic break may underline motives.
Emphasize following notes
Note(s) after the neumatic break will automatically receive emphasis.
