twocats You use the pedal to extend the notes, but "legato" means the notes are connected to each other in a smooth way. You can have the pedal down and play the notes staccato or in an obviously disconnected way, which would be non-legato with pedal applied. It's all about the attack on the notes.
Right. That's how I understood it "connected to each other in a smooth way.
Let's concentrate on "non-legato". I'd normally think of that as "not connected" - in other words, some level of staccato. But in legato I also see one note connected to the next note, but not all the notes piling on top of each other. A, B, C - the end of A blends a bit into B but then ceases; B blends a bit in to C but then ceases. We don't still hear A by the time C arrives. If the notes pile into each other, is that still legato, or has it stopped being legato from the other end?
If "non-legato" means that the notes must be separated as in some level of staccato, you'd not be able to achieve this by holding the pedal down. Therefore I saw "non-legato" as meaning that you can have the notes pile into each other.
Either that, or we have nonsensical instructions.
