Greatest Tone Poem? Don't Forget to Consider Smetana's "From Bohemia's Woods and Valleys"Smetana’s Ma Vlast constitutes the greatest orchestral score between Berlioz and Brahms. I don’t raise an eyebrow if you would like to correct that to “between Beethoven and Mahler”. And the jewel in the crown is “From Bohemia’s Woods and Valleys”.
