"Für Elise" was originally a piano piece composed by German composer Beethoven in 1810. The author dedicated this exquisite piano piece to the female student Therese Malfati. The music is written in rondo form. The theme that appears at the beginning is simple and friendly, depicting the image of a gentle, beautiful, simple and lively girl. This theme is repeated three times, with two contrasting interludes in between. The first insert is based on the new tonality, with bright tones, expressing joyful emotions; the second insert, set against the fixed bass of the left hand, is dark in color and strong in rhythm, making the music appear serious and firm. A series of ascending triplets and then smooth and lively descending chromatic tones naturally lead to the third recurrence of the theme. The music ends in a joyful and bright atmosphere.
