Re: \override vs. \overrideProperty

[Mats Bengtsson]

As far as I understand, a property value that you specify with \override
is stored in the context and copied to a layout object when it is created.
Once the layout object has been created, you cannot change any property
value using \override. \overrideProperty, on the other hand, allows you to
change the property value of an already created object. So, 
\overrideProperty
may be useful for long-lived objects, like spanners.
