Clefs and Notes

Hey, all! I am an unpublished writer and first soprano who is working on a children's chapter book that is LADEN with musical terms. Since there's so many, I have decided to write a glossery for the story to explain all these terms but I need some pictures or how to type these symbols:

- Treble Clef

- Bass Clef

- Whole note

- Half note

- Dotted quarter note

- Eighth note

- Flat

- Sharp

- Repeat

- Measure

So, anyone know where I can get some pictures where I won't have to go through a copyright deal, or better yet, know how to type them? Do I need a special program to do it?

Thanks all!
