"Cliffs of Dover" is an instrumental composition by guitarist Eric Johnson which appeared on his 1990 Ah Via Musicom album. The album version of the song is composed in the key of G major, the song was played with a Gibson ES-335 (as well as a ) through a B.K. Butler Tube Driver and an Echoplex plugged into a 100-watt Marshall amplifier. The song takes its name from the White Cliffs of Dover, an extensive and visually stunning chalk outcrop that runs along the southeast coast of England. It is also featured on the video game Guitar Hero III and is available as DLC for the game Rocksmith.

"Cliffs of Dover" begins with an ad-libbed electric guitar solo, using techniques such as string skipping and hybrid picking. In the solo intro, Johnson does not adhere to any distinct time signature. Drums are then added as the song settles into a 4/4 rhythmic shuffle verse accompanied by a very accessible set of melodies that, throughout the song intro, feature variations (octavations for example) on the main chorus.

The outro or coda then recalls the freestyle mood and timing of the ad-libbed intro.

While he did indeed compose "Cliffs of Dover", Johnson does not take full credit, saying "I don't even know if I can take credit for writing 'Cliffs of Dover' ... it was just there for me one day ... literally wrote in five minutes ... kind of a gift from a higher place that all of us are eligible for. We just have to listen for it and be available to receive it."
