Ascend and descend technique

[romanticshred]

I have this kind of sound in my head for some time.

Are there any piano exercise book which shows how to play Runs and Arpeggios ascending and descending at the same time?

I have recorded a few studied of my own recently today.

The transacription of the Aquarium from Saint-Seans Carnival of the Animals makes a great little study in this tech. A more thorough study of this tech is Czerny School of Velocity #36.
