I was about to suggest Haydn heheheh.
Try Mozart's D major sonata, K 284.
You might hate it though.
Really though, Haydn and Mozart, Haydn and Mozart, Haydn and Mozart.
Then there's the brief 30 sec prelude to Liszt's Pagannini etudes, which is all scales in intervals.
Beethoven op 10 no 1 (2nd and 3rd movements particularly) have their share of scale configurations.
Yeah, Scarlatti is definitley a great option.
There is a Moskowski piece Horowitz plays (I believe it's Etude in A flat major) that has massave scalework, and is speedy as hell, but you can slow it down.
That would be great actually.
