Rather than offering tips for performing this piece, I will outline common pitfalls.

1. Performance where the melody line and accompaniment are indistinguishable

The melody line should be clearly balanced so that it is discernible to any listener.

2. Performance with no dynamic variation from beginning to end

There are six phrases. Within these, determine which line is the most serene and which has the highest tension, ensuring that dynamics are not constant. Consider many factors, such as the current key, and within each phrase, identifying notes with low and high tension to give them direction.

For example, the sixth phrase, starting from measure 28, begins on D and reaches an octave higher D in measure 30. During this, the left hand gradually separates from the right, increasing tension. Once the peak is reached, from measure 31 onwards, it gradually descends to F#, so the accompaniment should support this as well.

Also, be careful never to place an accent on the final note of each phrase.

3. Performance where the second repetition is identical to the first

Some kind of variation is desired. For the second repetition, aim to introduce some difference, such as bringing out inner voices or playing the entire section pp.
