Music Toy

What is this music piece called from Toy Story 2?

It’s from the opening scene when buzz lightyear goes looking for zurg, and buzz jumps on the stepping stones…as he jumps on the stepping stones, this really familiar theme plays…What is it called??? please help~

It’s the same theme from 2010 A Space Odyssey. But I don’t know what the title of it is. It’s an old movie and that music has been used in a lot of other movies and shows. So, if you haven’t seen 2010 you probably heard it in another movie.
