Learn the basic concepts of improvisation from Gary Burton, one of the most renowned improvisers in the jazz world, including the mental, melodic, and harmonic processes that contribute to the instinctive skills that an improviser puts to use when taking a solo.
This is a very important opportunity to get into jazz improvisation, and if you are alredy playing some jazz music, this course have very nice tools for improvisation such as scales, harmony and "theme and variations" melodies that you can applay to any musical instrument.
Hard! Enough info to keep you working for a year to master it all. Like - "here are the ten most common scales" - all the modes plus three others the jazz folks invented - "learn these six well enough to noodle on them in one week." And the other 4 the next week. Not possible unless you are already quite familiar with most of them.
Also - some students were confused, this is strictly jazz, not improv in other genres of music.
As to being an "introduction" - maybe if you are already a fairly accomplished jazz musician! All the rest of us are going to WORK at this one and be overwhelmed. But it's all good material.
