Beautiful. Naturally, the pianist insists and explains in their own way the relationship between duration and intensity of sound. That is what creates the "continuity" on our instrument. We do not possess a "bow," but we must feel the continuity of the sound that becomes cantabile. The hammers have the task of exciting the strings, but they interrupt the continuity. We always hear in our ears and in our hearts the voice of our teachers who continuously said... "sing!". At first, one does not quite understand what on earth they wanted to demand because we were more attentive and worried about "taking" the notes. Over time, singing must enter within us and must take on a prevailing and, above all, logical value. In the examples, the Maestro performs bodily gestures that caress the melody, praising the "closure" of the sounds. The singing, the phrase, must convince us and must be convincing and must not have a "timid" and ambiguous appearance.
