Can I plug in my music keyboard and record onto the MacBook Pro 13"?

So I'm a music student and I wanted to know if the MacBook Pro 13" is good to use for program's such as GarageBand, Sibelius and Amadeus etc. Can I plug in my keyboard and record onto it? I'm a little unsure of its specs when it comes to using it for music courses and music in general. Thanks for your help.
