Anyone who’s a music lover should check out the Russian composer Sergei Prokofiev’s Violin Concerto No. 1 in D Major.
It’s an outstanding composition whose first movement gets feverish as well as lightheartedly lovely, whose second movement is strikingly jaunty, and whose third movement is poignant and highly melodic. It may be the best thing Prokofiev ever wrote.
For pared-down strings, I recommend Leos Janacek’s String Quartet No. 1 (inspired by the Tolstoy story, “The Kreutzer Sonata”)–just as rich and accessible as the Prokofiev piece.
