One of my very committed students found time in amongst the 12 hours a day of solid practise(!) to compile this rather good summary of how to play rootless voicings on the piano. It covers the basic build of each function type as well as some ideas of how to approach the subject from other angles.
I though I would share it with you as it sums up in 2 pages what sometimes takes a whole chapter (or book) to cover.
Enjoy, Mark
