String quartet, which is exemplified by Joseph Haydn, can be said had developed closely along the footsteps with the Vienna School of classical music. String Quartet No. 4 of Mozart was composed in Milan, while the composer was still a teenager creating opera works. Even so, the authentic instrumental vocabularies are still shown in the typical interval combination coming from the vocal ensemble, with its melodies lively and thriving, making listeners joyful and delighted. As for Beethoven’s string quartet No. 1, which is actually his second, it was carefully delivered after several changes. As a result, it conquered people within a heartbeat with the enthusiasm and magnificent pride in it. Smetana's From My Life is the song of life, full of joy and sorrow, with romantic longing and the folk tunes in it, and more specific and thrilling description of going through tinnitus and deafness. There are profound thinking and the hope of rebirth from despair in this work. The three classics are three witnesses of three different wonderful lives. Welcome to explore with us!
