This popped up on YouTube and I thought it was an interesting video. In it, several piano teachers are blind-folded and asked to play different pianos and guess if they were digital or acoustic. The tested pianos are mainly Kawai branded but there was also a Roland and a Casio in the mix. There are English subtitles.

If this video has already been posted, my apologies for reposting.

It has already been posted on a previous thread of mine as a reply but there's no harm in reposting it.


Finally bought the P515

My patience for videos tops out around thirty seconds. Unless there's a cat in it. Is there a cat in it?

Anyone care to summarize?

I must remember to include cat content in all future piano videos.

Here is a tweet with a picture that includes a piano and a cat. I hope it helps.

OK, I've been spot watching. The bits I've seen, seems like most folks don't have any trouble telling the difference, not surprising. Only the hybrid or hybrid-ish pianos (let's not get into THAT debate again ... ) such as the Kawai NV5 and the Casio GP gave much pause, and even then, were eventually identified by most. I wonder how much of that was by sound rather than the action (at least one person said just that).

In person it's not at all hard to distinguish an acoustic from a digital.
In a recording it's not as easy.

The sense of sonic space around an acoustic is lost in the recording.
The digital never had that sonic space, so the playing field is leveled.

But there are still shortcomings in a digital ... so the ability to distinguish depends on which digital is used.

And they were blindfolded so only could play random notes.

If was the piano covered with some fabric and they able to play properly, even the hybrids would be pinpointed easily.

One point is the sustain pedal is not used. Hearing sympathetic resonance could add a clue to distinguish digital and acoustic pianos.

It would have been easier if they stepped on the damper pedal, or were they not allowed to?

I think the fact that most of them had a relatively long pause at the NV5 serves a testament to how great this piano is.

At 3:43 and 8:10 the Kawai NV-5 even fooled 2 clients.

But at 6000€, I think I would prefer the Yamaha N1X and its grand piano action (7000€).

The ladies did not play these pianos, only trying out separate notes, and still were correct in most cases. iIf they were able to play advanced pieces, hybrids would not remain unrecognized for long, and definitely not forever

I think I would too. You get a grand action, plus key sensors which the nv5 lacks, this gives benefits like triggering different release samples by measurement of the key release velocity.

I agree. I mostly wonder how much of that is from the sound vs. the action.

One lady said the action felt very similar on all of them, and that it was the sound that she was making her guess on.

THanks, I don't think I heard that exactly, just one person mentioning that about one piano. For me that's good news, since I never expect a DP to sound like an AP, and just want something to practice on.
