FTP, these are all what kind of orchestral composition by the composer of Finlandia?
One of these works was commissioned on the occasion of the composer's own fiftieth birthday; that composer wrote that he wished to include "earth, worms and misery, fortissimo and sordinos" while working on the first of three versions of that work. A C/F-sharp tritone figures prominently in the third of these works, and a melody imitating a swan call occurs in the final third movement of the fifth of these compositions. The first one opens with a solo clarinet rhapsody accompanied only by an extremely soft timpani roll; that rhapsody is recapitulated in the strings  at the opening of the fourth movement, which is in E minor. The eighth one of these, much like the B minor eighth work of another composer, was unfinished, and material from it may have been reworked into the tone poem Tapiola.
