The images below show the rules of the standard smart playlists that an iTunes library starts out with and can be used as a guide to rebuild any of them you may have deleted or modified in error. Click on an image to see it in more detail.
To rebuild any of the lists use File > New Smart Playlist... and then enter the rules as shown. With iTunes 11 you may need to press Alt or Ctrl+B to access the menu bar (and optionally Ctrl+S to enable the playlist sidebar). As you change options in each row, working from left to right, the relevant selection boxes or value fields will appear. Use the + symbol to create a new line, - to remove one and the ellipsis ... to create a new subclause. It is probably best to use these controls to recreate the overall row structure before setting the individual options. When you have finished entering the rules click OK and then give the playlist its name.

The original definition for this contains many rules which match with the word "Classical" in different languages. When rebuilding it for your own needs it may be better to include alternate classical styles, e.g. opera, choral, baroque etc.
