What instruments are used in the song 'so long farewell' from the sound of music?

Ah, what a lovely question. In the song "So Long, Farewell" from The Sound of Music, you'll hear a variety of instruments playing together harmoniously. Listen closely and you may hear the sounds of strings like violins and cellos, woodwinds like flutes and clarinets, and brass instruments like trumpets and trombones all coming together to create a beautiful musical moment. It's like a happy little orchestra painting a delightful picture with their music.
