I bought 3 volumes of the method. Both the Volume 2 is dense and tasteless, as it is inconsistent. To play a note, you are advised, for example, do not press the wrong keys. There repetitions and forward references. On some aspects, it is hardly a method of notation for primary school pupils. Between songs, the CD is studded advice like "do not forget to clean your saxophone", "press any key at the same time."
Remember, aim instead on the "saxophone for Dummies" or "Method jazz sax - Vol 1." Goldberg!
