jazz and legit share much of the same teachings,regarding basics,liebs studied with allard,a classical teacher, and so did many other sax players in the north east.the classical teachers have a more focused agenda,certain tone,certain interpretation,plain certain,jazz teachers,i can say ie. lee konitz would enjoy what the student developed on his own,within a wide boundary,jazz builds in a certain freedom that sets up a school of its own,i love the sound classical sax players get.so of course i can learn from this.i love the sound of other studied players,whatever bag,i think the divide,classical jazz is a lot less then it was in the 50s,jazz and classical are intersecting in a lot of the music being played in europe under the jazz title.improvisation is nothing new to classical music.
