I've been studying jazz and what I've always been working on is understanding further knowledge on voicings and inversions. I've learned the major and minor triads, and root, 1st, and 2nd inversions. However, I know there is more on that, especially for jazz extended harmonies like I saw in the chord melody jazz tutorials (CMaj7 and ?? 1st inversion CMaj7 ??), and even learned slightly all through the internet and youtube on shell voicings. There are also what I found out called SPREAD voicings.

Any tips on how to understand better on extended harmony inversions, shell voicings, spread voicings, and any other I don't know of? 

Can this website probably upload new videos about this topic in the future? 

(Or maybe I've missed something and didn't delve deep enough here in the site, since I am a fast pacer lol)

Thanks
