This next microsong introduces two new features: the ternary bar signature and the rhythm figure lasting three beats, the dotted half note. It is likely that, in your music theory classes, you learned that the increase point causes an effect on the rhythm figures that precede it: the note is increased by the value of its own half. For example, a dotted half note would be 2 + 1, therefore 3 beats. Each note in this lesson will fill the entire measure. Think about counting mentally, for each note: 1, 2, 3… The rhythm must be stable and constant. The notes you will play will be C, D, E, F and G. At this point in your musical development, you should have already assimilated the fingering of these 5 notes. The title of the song pays homage to the Rio Doce, its tributaries and the people who depend on it. Good luck!
