Traditionally, the first step in most Buddhist schools requires taking refuge in the Three Jewels (Sanskrit: tri-ratna, Pāli: ti-ratana)[web 19] as the foundation of one's religious practice. The practice of taking refuge on behalf of young or even unborn children is mentioned in the Majjhima Nikaya, recognized by most scholars as an early text (cf. Infant baptism). Tibetan Buddhism sometimes adds a fourth refuge, in the lama. In Mahayana, the person who chooses the bodhisattva path makes a vow or pledge, considered the ultimate expression of compassion. In Mahayana, too, the Three Jewels are perceived as possessed of an eternal and unchanging essence and as having an irreversible effect: "The Three Jewels have the quality of excellence. Just as real jewels never change their faculty and goodness, whether praised or reviled, so are the Three Jewels (Refuges), because they have an eternal and immutable essence. These Three Jewels bring a fruition that is changeless, for once one has reached Buddhahood, there is no possibility of falling back to suffering.

What is the first step in a school of Buddhism?
Answer: the Three Jewels

With his mazurkas and polonaises, Chopin has been credited with introducing to music a new sense of nationalism. Schumann, in his 1836 review of the piano concertos, highlighted the composer's strong feelings for his native Poland, writing that "Now that the Poles are in deep mourning [after the failure of the November 1830 rising], their appeal to us artists is even stronger ... If the mighty autocrat in the north [i.e. Nicholas I of Russia] could know that in Chopin's works, in the simple strains of his mazurkas, there lurks a dangerous enemy, he would place a ban on his music. Chopin's works are cannon buried in flowers!" The biography of Chopin published in 1863 under the name of Franz Liszt (but probably written by Carolyne zu Sayn-Wittgenstein) claims that Chopin "must be ranked first among the first musicians ... individualizing in themselves the poetic sense of an entire nation."

Chopin was noted as introducing music to what?
Answer:
sense of nationalism
