It is by Ed Arkin and is called "Creative Chord Substitution." It is an
outstanding book, covering diatonic and chromatic chord substitution. It
goes fairly in depth, with an explanation as to why a particular chord was
used in place of another one.
Someone had asked about substitutions for "static" changes. He has some very
good ideas on doing this over tunes like "Girl from Ipanema" where the I
chord is played for two measures before resolving to the II chord.
Anyway, enough said. Anyone who gets an opportunity should check out this
book. It runs for about $15.00 and is available through Belwin Mills
publications (a division of Warner Bros. publications).
