Meditation is an interlude played between the first scene and the second scene in the second act of Masnier's opera Tess, so it is also called Tess Meditation, which is often played alone and has become an enduring masterpiece in violin solo, and also a masterpiece of Masnier. This episode shows the Thai people's mentality when they are tired of secularism and seek liberation through religious belief. This beautiful melody is not only used as an episode, but also often appears in plays to improve the atmosphere. The music is simple in structure, andante pious, in D major, with 4/4 beats. The first piece of music was quiet and peaceful, and the main violin played a famous lyric theme, just like a girl who opened her heart to the emperor devoutly and asked for the emperor's forgiveness. In the second paragraph of the music, tone sandhi was used several times, which made the mood of the music very unstable. It shows Des's surging thoughts and inner contradictions and struggles. The third song was calm again, the original melody appeared again, and the pious prayer was realized. Finally, the violin is pushed to the high-pitched area, gradually weakening the sound force on the G string, and ending with the faint sound of overtones slowly disappearing. It seems that the purified soul flies to the upper bound, which is the spiritual satisfaction of the reverie of a beautiful kingdom of heaven.
