The differences between these exercises and the ones of the previous lesson, stands in the employment of the five notes (from C to G) for both hands. It’s a four-four time and the time is moderato. My only warnings for you are to be faithful to the refrain in the example no. 14, while in the no. 15 you will have to pay attention to the three dot notes, that is the three G in the fourth measure.
They must be executed for half of their value, 1/8 each crotchet.
