Felix Mendelssohn said this quote

People usually complain that music is so ambiguous, and what they are supposed to think when they hear it is so unclear, while words are understood by everyone. But for me it is exactly the opposite...what the music I love expresses to me are thoughts not to indefinite for words, but rather too definite.

~ Felix Mendelssohn

People often complain that music is too ambiguous, that what they should think when they hear it is so unclear, whereas everyone understands words. With me, it is exactly the opposite, and not only with regard to an entire speech but also with individual words.
