sight singing "Clementine" melody

Today's lesson gives you sight singing practice in D major with a compound meter.  The time signature is 9/8 which means that there are 9 eighth notes in each measure and the dotted quarter note gets the beat.  The melody is a combination of stepwise motion and skips that outline the I (one) and V7 (five seven) chords.  In the key D major the I chord is D  (D, F#, A) and the V7 chord is A7 (A, C#, E, G).
