it is a long list of official teachers, like george szell who was my mentor, wolfganag vacano startingime i was 10 or 11, i had walter levine with all the musical -- for everything, for theory, for harmony for style. he even coached me on the instrument, playing chamber music with his students. it was an unbelievable education of the kinds that one goes to college for, but i was 11 when i started. then, i went, for example to marlborough. there was claude frank and able community of brilliant teaching musicians. then i went to aspen to study with rosina levine because she was the most dynamic teacher of the instrument at the time. she was very well known for working on technique, but she took me, knowing full well that i was trying to use the piano as a tool for conducting mostly. i didn't know how much i wanted to perform on the piano. it turned out i did want to and did do quite a lot more than i pictured when i started. she was very willing to start with me when i was 14, the year after i was with -- in aspen, darius milhaud, he brought contemporary composers within every summer. on
