You might try my book "The Most Advanced Clarinet Book". You can practice it slowly or even a measure at a time. 50 short studies with explanations of these difficult techniques. Then 27 full page etudes. 49 pages. Descriptions, etc. should be on Austin Macauley (publisher) website after it's release April 30, 2018. It can be ordered from numerous online places including Bookmasters of Ashland, Ohio.
I've played through the Hite Book--good stuff. He also has a flute method that is very good for clarinet high notes. Another very advanced method is the several Jettl books. Very difficult.
