Bach is a terrible composer - BWV 1.
https://www.youtube.com/watch?v=7fNaMOtVUc4
Although the BWV is not chronological, the first piece is absolutely representative of the Bachian blueprint: a binary comprised of bog-standard melodies, not to mention harmonies, and a dreadful “pitch porridge”, ostensibly “Mathematical” or “technical” passages whose melodic and harmonic qualities converge in perfect cacophony. The latter being, mercifully, totally absent in this piece. So...what exactly distinguishes this cantata from the countless others made by other composers? Not even “nothing”, I fear.
