All of these are photos of my families more than hundred year old piano in our family room.
f/3.5
This photo had a small aperture (large opening), and because of this there is a small depth of field and much of the photo is out of focus.
f/10
This photo had a medium aperture, and while the music book and ledge of the piano are focused, some of the keys is out of focus.
f/22
My final photo had a large aperture (small opening) and the whole photo was in focus, showing that there was a large depth of field.
