Debussy Pour le Piano Glissandi

[h_chopin148]

I'm learning Debussy Pour le Piano right now and I'm working on the prelude. My teacher is currently away so I am practicing on my own. I was wondering how I should play the glissandi and in the prelude without injuring myself. This is the first piece I've played with glissandi in it. Any help would be appreciated!

you are suppossed to play them only with your nails and nothing else.

1.if its white-key, use the edge of your 2nd finger
2. if its black-key, use the edge of your thumb
