I sincerely consider Mendesslohn as a romantic composer and not as Beethoven "in between" the previous period. Anyway, it is true that his style is more "clean" and "linear" than the typical romantic composer like Chopin, Liszt, Brahms and many others.
About Chopin, he was the first composer introducing "free-little" cadenzas inside the compositions and actually he began to broke the tradition of the "quadratura" (I don`t know how to say in English) of the 4+4 bars musical period... he was really a pioneer like Beethoven was.
Thank you for your discussions!
Sincerely,
Fabrizio.
