Interested in learning jazz? There are some great jazz piano lessons.
If you're really interested in being a great (or good) jazz player, the
first thing I recommend is the Jazz
101 course by Hear and Play.
Jazz is not simple. It takes some structure to learn. There are some
good free lessons online but the trick is learning in the right order.
Here are some of the good video jazz lessons. (Not for complete
beginners - try to learn chords and the notes of the piano keyboard
first.)
A little more advanced, a jazz/blues improv lesson.
There are many more videos. You can search below to find others that
suit your level. Again, if you're a beginner, check out the Jazz
101
course. It's really good.
Also, check out the page on jazz
chords.
