Classical Gas is one of the most requested and most familiar instrumental pieces of all time. In an episode of The Simpsons called “Last Exit to Springfield” Homer leads the workers of the nuclear power plant in a strike to recover their lost dental plan. While they picket the plant, Lisa plays a bleak worker\’s song. As she finishes, Lenny shouts, “Play Classical Gas”. Lisa plays the guitar and everybody watching the episode on TV goes, “Oh, yeah, THAT tune!” Classical Gas is always asked for whenever a bunch of people and a nylon string acoustic guitar are in the same room. It is not really a great technical showcase for finger style guitarists but it is a great vehicle to show off the sound of the classical guitar.

Classical Gas was released into the world in 1968. A song by The Doors prevented it from turning into a number one hit but it remained in the second place for two weeks. Forty years later it is still among the most familiar tunes of all time and, along with The Anonymous Romance and Leucona\’s Malaguena regarded as an essential element of the classical guitar repertoire. And nobody can say why.

The impact of Classical Gas is way more than the sum of its parts. There are very few musical ideas in the tune. It is mainly repetition of a theme made up of a few notes. There are a few parts that are unforgettable “surprises” making use of syncopation, scales, strums, and abrupt time signature changes. Somehow all the bits link together like pearls on a necklace, and the final note adds a sublime resolution.
