My tastes tends to more modern classical music - from say late 19th century to, in the main, mid 20th century. Mahler, Bruckner, Bartok, Shostakovich, John Adams (even more recent), Copland, Bernstein. But then, of course, there's Beethoven.
The Baroque period has my favourite composer although do suppose Bach is a little mainstream for INTJs. However, only Purcell comes to mind for anything earlier than Vivaldi; you start seeing some good names after he gets into it. Then you have a whole lot to choose from in the Classical period but the story telling just takes off from nowhere once the wind instruments start developing and you have guys like Berlios, Dvorak and all those Russians who just go crazy with it....
Okay I can choose. Mendelssohn screws with my head in strange ways. One vote for early Romantic.
No specific timeline as long as it's romantic. My ENTJ friend is a musical genius and plays a lot of classical, so I get to see ALL these pieces performed for me on a regular basis on the piano. She doesn't just play music though. She is the embodiment of her music. I love it :laughing:
I'm not yet sure what I am, so this might not be a fellow INTJ but an INTP posting.
It's tough for me to pick an era. My favourite composers are Wagner, Mozart, Mahler, Bach, Händel & Beethoven. I also enjoy Strauss (the Last Songs in particular), Chopin and some Haydn. I don't like most modern classical music. I go through phases; I once decided to listen to all of Bach's cantatas (only got about halfway, there are over 200!), so I imagine Baroque would have been my favourite era then.
Recently, I listened to most of Richard Wagner's Operas and I'm currently going through a bit of a Mahler & Strauss mini-phase, so I'm going to say the Romantic era's the one I enjoy most at the moment.
