Pyotr Tchaikovsky's (1840-1893) Symphony No. 5 in E minor was influenced by his own self doubt and idée fixe, a reflection of his admiration for Berlioz. He saw Mozart as the best of the best and believed that he would never reach such greatness. He also wanted this symphony to be similar to those of Berlioz's symphonic poems. His Symphony No. 5 was also very controversial at the time. Being from the Romantic period, motivic development and following the rules of counterpoint were not necessities to make a great symphony.
Abraham Zvi Idelsohn (1882-1938) was the first person to transpose the Jewish folk song Havah Nagilah. It began as a Hasidic melody and was later adopted by Sephardi Jews in the 1940s. The tune was a nigun, a wordless melody, and used by the Sadigorer Hasidim to express joy. Havah Nagilah developed as a song to be used in celebrations like weddings and Bar and Bat Mitvoz. The tune was likely inspired by the psalm: “this is the day the Lord has made, let us rejoice and be glad on it.”
