3. Repeat the first four bars.

4. Four bars to the end.

Three children can be used for this, in the following way:

The first child sings the first four bars, the second goes on to the end
of the eighth bar, then the first child repeats what she sang, and a
third child finishes. This affords excellent practice, particularly for
the first child, who soon learns to confine herself to a simple opening,
as this must be remembered and repeated later.

Memory plays a much larger part in the power to extemporize than many
people realize, and if this step in the preliminary work be
conscientiously taken there will be abundant results later.

We now come to the important stage of extemporizing on the piano. It
must be remembered that a very thorough foundation of the knowledge of
chords has been laid by the ear-training work, leading up to the power
to write down chords from dictation, and to sing them in arpeggio.

The first exercise will consist in playing a very simple tonic and
dominant accompaniment on the piano, while a melody is extemporized with
the voice. There is far more variety possible in this than appears at
first sight. For instance, the sequence of the chords may run in any of
the following ways, among others:

I V I V I I V I }
}
I I V I I I V I }
