Wieniawski was a Polish composer. Even though he came from a jewish family, his father converted to catholocism. Wieniawski's violin talent was quickly discovere, in 1843 he attended the conservatory of Paris at the age of 8. After he graduated, Wieniawski went on tour giving many recitals. He was often accompanied by his brother, Józef. In 1847, he published his first work, the Grand Caprice Fantastique.
On invitation by Anton Rubinstein, Wieniawski moved to St. Petersburg where he stayed until 1872. There, he taught a large number of violin students, led the Russian Musical Society's orchestra and string quartet. Fro, 1872 to 1874, Wieniawski toured throughout the United States together with Rubinstein and in 1875, he replaced Henri Vieuxtemps as a violin teacher at the conservatory of Brussels. In Brussels, his health declined fast, which at one time forced him to stop a performance midway through. He gave his farewell concert in 1879. A year later he died from a heart attack in Moscow.
Johann Sebastian Bach was a German composer and musician of the Baroque period. He enriched established German styles through his skill in counterpoint, harmonic and motivic organisation, and the adaptation of rhythms, forms, and textures from abroad, particularly from Italy and France. Bach's compositions include the Brandenburg Concertos, the Goldberg Variations, the Mass in B minor, two Passions, and hundreds of cantatas. His music is revered for its technical command, artistic beauty, and intellectual depth.
Bach's abilities as an organist were highly respected during his lifetime, although he was not widely recognised as a great composer until a revival of interest in and performances of his music in the first half of the 19th century. He is now generally regarded as one of the greatest composers of all time.
