Great job today, boys!!

Ahaan

Really happy with your progress and exuberant attitude, Ahaan!  Even though moving to the rhythm while playing seems foreign to you right now, if you keep practicing it, you will soon get it, and become a master at it.  I promise you!!

Mazin

Tense up your core/torso muscles so that your playing apparatus can be free to play as required (either tense or relaxed depending on what you are playing).  Shoulders MUST be RELAXED, ALWAYS.  Remember to articulate near the tip of your thumb!!

Gerardo

Same goes for you as Mazin, Gerardo — tense up your core/torso muscles so that your playing apparatus can be free to play as required (either tense or relaxed depending on what you are playing).  Articulate near tip of thumbs = HIGH wrists.  And, push wrists forward as your tummy tenses even more on the strong beat.  ACTIVE and full of motion hands and fingers for the hand playing the melody.
