Question
hi there,  I hope your knowledge of instruments includes electronic oriented type instruments because I was wondering if u know the instrument & perhaps even the note being played on it from this tv ad.      
( Ignore the sound of the piano being played )

p.s. it sounds - to me - like an electronic organ. Whatever it is, it's an euphoric kind of sound; perhaps the kind of sound that we hear when we go to heaven?  LoL

Answer
Hello Dan!  The sound you hear closely resembles a "celeste".  In pipe organs, the sound is created by pairing two similar ranks of pipes together.  One pipe rank is tuned to unison pitch (A440) and the other is intentionally tuned around 10 cents sharp (or flat).  The tonal results creates a rapid undulating sound as the pipes' many harmonics react to the untuned state by rapidly shifting in and out of phase.  In other words, the result of two pitches that are not in tune with each other will create a "shimmering" motion that has been described as "celestial" or "ethereal".  Because the effect is considered so desirable, some insist the celeste is the most over used stop on an organ.

Pianos as well can be made to "celeste" when one of the three strings is detuned.  The effect is referred to as rinky-tink.

Electronically generated celestes can use the same method of pairing two slightly dissimilar pitches together.  However, in many digital keyboard instruments, the celeste is created purely by electronic means which only approximates a genuine celeste, in which case it is typically referred to as a "celeste effect".

I believe the recording you referred me to is the latter, the digitally approximated variety.
An effective use of an electronic celeste can be heard at https://www.youtube.com/watch?v=IChJ6eO3k48
