Today's lesson gives you more practice with ear training in a minor key. The key is D minor with "la" as the tonic. The natural minor scale is ltdrmfsl. You'll notice that the tones are the same ones used in F major except that you start and end the scale on D which is "la". Just by changing the tonal center you move from a major mode into a minor one. Pretty cool!
The song in the lesson is called "Old Hungarian Round" which I first learned from an old Girl Scout songbook. I learned it in Kodaly training with different words and a dance. Listen to it sung as a round with the Girl Scout words.
