How do you put emotions into a Chopin piece?

Answer 1

A few ideas:

• Use rubato when applicable; many of his nocturnes give a lot of freedom in the fluctuation of tempo. Don't be afraid to sink and relax into the music.
• Pay attention to the dynamics and have a good feel for the progression of the piece (e.g. when parts should be played with strength/gentleness)
• Try linking the music to events or images, and play with whatever emotion it makes you feel.

And one more idea: Listen to some recordings of Chopin by pianists who are renowned for their interpretations of his music. Not to copy them, but to get an idea of how they do it.
