Hi Shho,
If you're using Notation Musician or Notation Composer, then you can have the note pitches (eg. C D, etc.) displayed in the notehead. You can do this a couple of different ways, depending on what you want to see on the score.
1. Parts/Prepare Easy Notes - this method gives you a single melody line of enlarged notes with the note names. You can select to show chord names as well.
2. If you have multiple staves, or staves with chorded notes in them, you can use Format/Display pitch names in noteheads. You can change the size of the notes in Format/Font styles, and choose "Music symbols" in the lower left box. Set the size to whatever is comfortable for you.
Enjoy
