Desert Island with a Twist - 2

[Florestan]

Obviously this depends on which country you choose for the desert island and how shameless you are about claiming an extra composer  0:)

Well, Mahler, though clearly not a Czech proper, was technically a native of the same country as Smetana and Dvorak, namely the Austrian Empire --- so you can keep him.

Germany/Austria purely for the huge variety of music over a long period of time.

You could start with Hildegard von Bingen I suppose (not really a fan) and work your way through Telemann, all the Bachs but mainly JS, Handel, Gluck, Haydn, Mozart, Beethoven, Hummel, Schubert, Schumann, Mendelssohn, Wagner, Brahms, Bruckner, the Strauss' and I've not mentioned the slightly lesser knowns such as Reger, Bruch, Czerny, and others.

If this was all the music I had available to listen to for the rest of my life I wouldn't be unhappy. I also can't see any other nationality matching this output, including the French and Italians.

Can't see a solution here. I think I'll have to start my own country and offer posthumous citizenship to every composer that's important to me. Just have to find an uncharted island somewhere....

And tehnically speaking you'll have lots of Czech and a few but important Hungarian composers as well. 

That is my answer too. The only non-Austrian/German composers I'd miss would be Chopin, Tchaikovsky and Rachmaninoff.

[(poco) Sforzando]

While I would miss France and Italy, it would have to be Austria-Germany.
