Frédéric Chopin - Nocturne in B Major, Op. 9, No. 3

It is in ternary form A-B-A. The first section is marked allegretto. The main theme is chromatic, but filled with nostalgic energy. The second contrasting section, Agitato in B minor, is a very dramatic one with a combined melody and counter-melody in the right hand and continuous 8th note arpeggios in the left, which requires an amount of virtuosity. The piece is full of coloratura ornaments, and ends with a wide chord in the left hand accompanied with right hand triplets in a high octave to lead to a legatissimo smorzando adagio (senza tempo).
