[mila5405]

Leaned from this video that the is a couple of different non legato touches  such as tenuto, portato, leggiero, brioso, jeu perlé and more.

Piano Masterclass on Non-Legato touches, from Steinway Hall London

So here´s my question.
Can anyone hear what kind of touch the pianist using in this audio example

Forgive me for I am a bit of a beginner still, but isn't this something that can't really be determined scientifically? Or objectively? It's not black and white?

In the scalar runs?  I'd just call that legato.  If I were to notate it, I'd probably put dots over/under the heads of the notes, and have the entire run under a "slur" or whatever it's called to indicate legato but with clean articulation.  That's how I'd expect others to notate it as well.

As should be clear, I don't exactly have the terminology right. 

I can't hear well enough from the clip if the pianist is "finger-pedalling" or using a touch of the sustain pedal, but I'd guess a bit of both.  That's how I'd do it, anyway, with the end result approaching the "articulated but legato" idea.

I mean, like another poster said there's not really a scientific answer. But I'd play like what you're hearing in the recording if I was going for a leggiero/"jeu perlé" sound. The fundamental approach is legato, but with the notes detached from each other in a way that gives the impression of a bubbly lightness.
