An ostinato is a short, repeated rhythmic phrase. Ostinatos are a great way to practice rhythmic skills. In this case, we are also using the ostinato to remember where are landmark pitches are written. You can hear a recording of these three ostinato patterns on the website. There are also recordings of the ostinatos played in combination. Keep reviewing the landmark pitches, they are the foundation for much of the reading coming later in this book. If your child doesn’t seem confident with them, make flash cards with the treble clef notes on them (see the website for a how to video). Once you can play each line try putting them together. It is easy to trick yourself into thinking that you are playing a rhythm correctly, only to find out that when you put it with another rhythm you are not. By fitting rhythms together you can really hear the value of different rhythms.
