In order to achieve what he believed and felt through music, the Romantic composer had to convey his understanding to the performers by emphasizing the crucial need of musical expertise in the now expanding orchestra. It wasn't more of the Classical precision. It was an era of personal expression with heart. There was a need to feel, not just from composers but performers too. This is the path to musical appreciation. The intent was purely noble; capturing the audience by touching the listener.
Romantic performers felt the same as the composers of the time. While the composer conveyed his intent to the members of the orchestra, the musicians got it, understood it, and knew they had to get inside the listener. Without the style of the Romantic performers, music might never have really sent any message at all. Resultant were sound combinations which sent chills straight into the human soul and broke many a heart. A new kind of tear fell that day. Not one of sorrow but one which touched us and called to a part inside of us all that we needed to hear. We feel. We wonder. We love. It worked.
