Each line of a tab correspond to a piano octave.
An octave is a set of 8 white keys and 5 black keys, named respectively c,d,e,f,g,a,b and C,D,F,G,A.
As you can see, capital letters are for black keys. The C key in a tablature is actually a C# (c sharp) or a Db (d flat).
Playing a F which is on a line beginning with 4 mean playing the third black key of the 4th octave of the piano (which is in general the middle octave on the keyboard).
