Even though polyphony was no longer in fashion after the Baroque period, composers seemed to understand that it was the highest form of music. Nearly all composers, as they matured, ventured more and more into contrapuntal writing, taking pleasure in having several voice lines going at the same time, operating independent of each other but obeying the rules of harmony. Counterpoint, it turns out, works in any style and period of music.
As a composer myself, I can bear witness to the magnetic appeal of polyphony. The charm of multiple voices sounding at the same time but independent of one another is hard to resist. No composer worth his salt has avoided it for very long.
