Scott, 

I completely agree! I teach middle school and music theory. Would be a great resource for students to seek explanation of part writing, voice leading. I also would love to see content for quality tone production and instrumental technique. The possibilities are endless! 

I completely agree with Scott and CatchyMusic92.

I, along with several other students I know, would deeply appreciate this venture. If there is anything I can do to personally assist in bringing Music Theory in as another of Khan Academy's subjects, please contact me. 

Thanks.

Until Khan Academy expands the Music Theory section (on which they may be working as we speak, I don't know), Udemy has great music theory courses for $12 each.

The one I am taking right now is taught by a college professor, in a similar form as does Khan Academy. He's had over 6,000 students on the site, and from the ten lectures I've viewed (there are 152 in this course), I can tell you the $12 was a worthwhile investment.

I'm not sponsored or anything, just trying to help. However, I look forward to Khan Academy's expansion and cheer them on in that effort. 

YES! There are no videos about AP Music theory anywhere and Khan would be such a good place for them to be.

yes there is no doubt about it that KA has the best audiencehere and they are capable to do this job and i am sure that they will think about it in future and waiting for that time to participate in it.
