Hmm, as a general intro this is o.k. - but be aware that syntax is coupled with 
semantics
and with Lisp/Scheme sematically differnt things do have the same (non)syntax. 
Some
consider this elegant, some feel they get lost.
BTW, 'if', like 'let' or 'cond' or 'begin' etc.,  is _not_ a procedure but 
either a macro or a special
operator.

Autsch. Racket, DrScheme, MIT-Scheme, Bigloo, Chicken, Stalin, ChezScheme or, 
relevant
for us musicians S7 ...
