Glissando?

[mwf]

Hi

What does glissando mean or gliss as I have seen on a score, on suggestion diabolique for example there is a low note followed by a much higher note near the end of the piece a couple of times with a line slanting upwards between the low and high notes with gliss wrote above, what is this? does it mean a sweep with your hand upwards stupidly quickly?

yes ,, using your finger nail you slide from the low note up to the higher note, doesnt have to be played stupidly fast!

And can one explain how to do a double glissando? I've got a video of Hamelin doing HR No. 2 and his cadenza is quite breathtaking, I have no idea how he does this amazing feat... are there many other examples of the double gliss?

Oh yeh, i have that video and to tell you the truth i dont like his Cadenza,

...please dont hurt me!

By double glissando do you mean like playing c and g down the piano or something (In other words glissando two notes down instead of one) if you do, that is easy (i can only do that down, not up and i use thumb nail and finger 3 but not the nail with 3)

If you dont mean what i said above what do you mean

Thanks

in waldstein's finale is it supposed to be a glissando (the octaves going up and down) coz the reocrding i have plays it without glissando but i've seen a few people who play the section as a glissando
