Listening to music is a step-by-step process. From the beginning, you will find it difficult to understand and hard to hear the great works of Beethoven and other masters, which will lead to this kind of rejection. Therefore, you should listen to classical music selectively at the beginning, starting with sketches and sonatas, and then going to concertos, symphonies and operas. Vocal music begins with the transition from artistic songs to large-scale songs. Take Beethoven's works as an example. First listen to his To Alice and Moonlight Sonata, then listen to the violin sonata Spring and Violin Concerto in D major, and finally listen to his nine symphonies, so that you can easily accept them. A lot of classical music is very pleasant to listen to, besides Beethoven's works, there are Chopin's nocturnes, Mozart's piano sonatas, Schubert's artistic songs, Debussy's moonlight sonatas, Haydn's serenades, Chrysler's violin works and so on.
