356 Chapter 15 Score Editor
When you insert a “C-clef”, please watch the Help Tag carefully, as this clef can be
positioned at five different heights, depending on the register (alto, tenor clef, and so
on).
If you want to change an existing clef, double-click on it. This opens the following
selection box. (The same applies to the “basic” clef of a MIDI Region, but changing this
clef affects the Score Style itself, as well as all Regions that use the same Score Style).
The Smaller Clef Changes in Layout > Clefs & Signatures option also affects clef changes.
All clefs, except the first one in every staff, will be reduced in size, depending on the
value set here. This will happen, whether the clef changes are the result of a different
Score Style in the same staff, or clefs have been inserted from the Part box.
Octave Settings
The four symbols on the right hand side do exactly what you expect them to: they
mark a section to be played either one or two octaves higher (or lower). The length of
the section can be edited after insertion, by grabbing the end of the line and moving it
horizontally.
Dynamic Symbols
These symbols can be inserted at any position in the score. They are graphic symbols
only, and have no effect on the playback of Regions they are placed in.
