"Sense of Doubt" is an instrumental piece written by David Bowie in 1977 for the album "Heroes". It was the first of three instrumentals on Side Two of the original vinyl album that segued into one another, preceding "Moss Garden" and "Neuköln".
Cited as "portentous" and "thoroughly foreboding",[1][2] "Sense of Doubt" is one of the darker tracks of the album, with a descending four-note piano motif juxtaposed with "an eerie synth line like a scrap of sound from a silent expressionist-era soundtrack".[1]Brian Eno suggested that the contrasting themes were the result of him and Bowie each following an Oblique Strategies card to guide them in the track's overdubbing, Eno's directing him to "make everything as similar as possible" and Bowie's to "emphasize differences".[3]
"Sense of Doubt" was performed on the Italian TV programme L’altra domenica in 1977 and throughout the "Heroes" tour in 1978.[4]
