This song contains the nice C E G B (all natural or white piano key chord)
This chord is called C major 3rd major 7th.
It is writen in the scale re key of E minor. This means all notes are natural or white piano keys except F which is F sharp.
This is why when bass is C the chord is C E G B and not for example C E G bB as B natural belongs to the set of allowed notes defined by the key of E minor.
On this song many times the seventh (note B) with respect to bass (note C) is prepared (in advance) for the human ear brain so that the dissonant interval sounds amazing. The 3rd with respect to bass (note E) is added as explained by Bach making the disonant interval sound even more amazing to the human brain. See the Bach manual to his students, Bach Bass Rules.
When Bach was a teenager this manual had been given to him by engineer Niedt.
Had this not had happened would modern music sound as amazing as it does today?
