Sorry to bump this old thread, but I have Schoenberg's book and I have learned a lot from it. The problem is some of the examples I have no idea which ones he is referring to. For example, on page 120, in the middle of the page, he refers to Op. 2/2-IV (m. 1-16). What the hell page is that on? If he says Ex. 36 a, I can flip through and find it with no problem. Also, for another example, in Chapter three Ex. 21, he shows an example of how to reduce and omit features from a motive, but does not mention what the original motive was. He does that a lot in the first few chapters.
If anyone has this book and knows what I'm talking about, I'd like some help.
