Below you will find the chords for the popular standard, Route 66, a blues in G. Usually this song is sung in F, but I chose to write it out in G to match the first recording of the tune. For this particular version, I took the chords off of Nat King Cole’s 1946 album by the same name. I used “vanilla” chords, which is basically the least amount of substitutions, with the exception of the 10th measure of the break where I did notate an Ab7. The Ab7 is a tritone away from D7 and is also known as a tritone substitution.
