This is “Don’t Fear the Reaper”, a song by Blue Oyster Cult released in 1976, which makes it close to 40 years old. Wow. There is also an Apollo 440 cover (1995) which I think is pretty decent.
The basic tune, which is in the key of C, goes:
- A E A G
- G B D G
- F C D G
- A E A G
This guitar tab is a pretty good rendition of the tune, so I’ll quote the main part below as-is (just added the string names at the left side):
Am G F G e|------------------------------------- B|------------------------------------- G|-------2-0--------0--------0-------0- D|-----2----------0--------0-------0--- A|---0----------2--------3-------2----- E|------------3--------1-------3-------
Since only the top four strings of the guitar are used, the same tab can be used directly on bass guitar without any modifications.
