We looked at a Schoenberg piece in freshman theory where he used a
three-note tone row over and over again in both melodic and harmonic

I don't recall the piece, but it was pretty strict. The tone row was
not merely a melodic rule. The harmonic rules of his system may not
have been tonal, but they existed.
