I listen to Robert Greenberg's classical music appreciation audio courses. He has published courses on Bach, Mozart, Beethoven, Liszt, Schumann, Mahler, Verdi, Wagner, Stravinsky, Tchaikovsky and also on horizontal subjects such as orchestral, piano, opera, baroque music, romantic music, symphony and quartets (and much more).<p>Sample: <a href="https://youtu.be/whgu7nX0sZc?t=522" rel="nofollow">https://youtu.be/whgu7nX0sZc?t=522</a> (debunking some Shostakovich myths)<p>Greenberg is a gifted speaker, a composer and and music professor himself. He's sharing with us a burning passion for everything classical. If not for the informational content, then at the very least it's worth listening to him in order to infuse with his passion.<p>After taking some basic notions about composers and music genres, I started a YouTube safari for unknown music and composers, I am 7 years into my search already. I listened to hours of classical every day since I started. YT is a treasure trove of historical recordings, you can do comparative listening and refine your listening abilities.<p>There are so many composers almost nobody heard about, even professional musicians, that it's mind boggling. After all, there is a long history of classical music, hundreds of years in the making, and the level attained by Bach 300 years ago was already (and still remained to this day) cutting edge.<p>Imagine how interesting it would be to browse videos and papers from 300 years history of computer programming. We are overwhelmed even with the production of the last decade. Classical music has such a wonderful deep history that is endlessly entertaining.<p>A list of Robert Greenberg's courses is here: <a href="http://www.thegreatcourses.com/professors/robert-greenberg/" rel="nofollow">http://www.thegreatcourses.com/professors/robert-greenberg/</a>
