Yes, filling the time was important. It was easy to get lost in absolutely nothing while waiting for Grace to get home. Then once realizing he was actually putting life on hold just to wait for his daughter to get home, Jefferson saw this as a problem. The day needed to be filled and he needed to keep active and not vegetate. Grace had her own life to live and so did he. Preferably with her in it, regardless. "Music is more helpful and important than people realize. If you stick with it, you'll find it's the perfect thing to fill time with no matter what sort of mood you're in." He realized then that this could be interpreted as a biased opinion, pausing as he sat down in front of the piano, blinking and swiping idly with his wrist. "If it does end up being your thing."
Much as he could and would get philosophical about the art--because he could, passionately, Jefferson didn't want to turn this into that. They were seeing if this was something Emma enjoyed and he was supposed to teach. Not go on about his musical theories. "So have a seat and let's find out." He tapped the area beside him on the bench and lifted the cover of the keys....which were noted for teaching (this was one of a few pianos in the house actually) beginners as the cheats were marked on top of the keys. With colorful animal stickers. Thank you, Grace.
Jefferson's lips curled inwardly at the sight, remembering that he had told Grace she could mark the keys however she wanted (she was also learning) and well, this is what he got. Moving on with a clear of his throat, he motioned to the animal covered keys. "As you can see the major cords are marked and the...ducks and puppies should help with the memorization. Typically, your fingers will always rest here, wrist just above as if you were typing at a computer. Never rest your wrists against the keys."
