You can find on the first side of the book of music
or click on the tab "Form of music"
The rough musical form is represented with the help of rectangles which reflect the individual parts (here sections) of the composition.
By double-click open a dialog on a partial rectangle and work on the name of the part and further partial information there.
You can copy or move whole parts, in which you select a rectangle and move this to a new position with a depressed left mouse button. You are then asked whether the part should be copied or moved.
If you select a partial rectangle with the right mouse button, then they jump to the corresponding position of the score immediately.
