Comfortably Numb is one of the most popular songs from Pink Floyd’s album The Wall, released in 1970. It is one of only 3 songs on the album credited to both Roger Waters and David Gilmour. This lesson concentrates on just the rhythm guitar aspects of the song. We use a single strumming pattern that is very common in slower songs. The chords are from the keys of Bm (D major) and C, and give the student a good opportunity to work on bar chords.
