This piece, which uses only fingers 2, 3, and 4 in both hands, is suitable for practicing beautiful legato. Up to measure 8, the first note of each phrase begins with finger 2, but it is important to prepare all fingers 2, 3, and 4 in close contact with the keys. Transfer the weight from finger to finger, and it is crucial for the ear to clearly perceive not only the moment of striking the key but also the sustained sound. After playing, the finger does not lift from the key but quietly returns to a state of contact with the original key. With a calm mind, connect the physical sensation with the circuit of the emerging sound. This is a suitable teaching material for mastering only the truly necessary movements, and I believe it is a beneficial etude not only for children in the introductory phase but also for advanced learners and adults.
