What is portato in piano?
Portato is a bowing technique for stringed instruments, in which successive notes are gently re-articulated while being joined under a single continuing bow stroke. It achieves a kind of pulsation or undulation, rather than separating the notes. ... a slur that encompasses a phrase of tenuto notes (less common).
What does non legato mean in piano?
non legato is just that - not smoothly. This does not necesarrily imply staccato. Just put 'staccato' out of your mind when trying to deal with non legato and think of it as how the notes sound when you play them normally, with no attempt at legato or staccato.
