Well, how basic do you want?

The most basic two tutorials that I know of are "The Little Schemer" and 
"The Seasoned Schemer"--the first author is Friedman for both.  I highly 
recommend "The Little Schemer" in spite of its somewhat juvenile nature. 
  You don't really notice it because you get pay more attention to 
typing in the vast number of code examples.

Apparently, there is another book called "The Reasoned Schemer" that 
just came out that covers some added logic constructs (a la Prolog) to 
Scheme.  I cannot comment on it as I have never seen it; I just noticed 
it on Amazon.

I know that someone recommended "The Structure and Interpretation of 
Computer Programs."  It's a good book and lots of people like it.  I 
don't actually dislike it, but, for some reason, it never really 
resonated with me.

I actually thought "Common Lisp: A Gentle Introduction to Symbolic 
Computation" by David S. Touretzky was better.  It is also available 
online: http://www.cs.cmu.edu/~dst/LispBook/
