I bought this yesterday and I'm determined to do the etudes and practices daily and kiss mediocrity goodbye. I am a lazy man and playing scales and arpeggios is something I find quite impossible to do. But the key to good performance lies in consistent hard work. I used to work on Baermann and Otto Langey but I'm getting tired of them. A change of scene is what I need. And although they say you shouldn't judge a book by its cover, I think this cover is pretty good. It encourages me to pick up my clarinet. At least for now.
