I had a chance to play around with discord. There are a few limitations, but it could be a promising tool if students were inclined to collaborate.
It's not really a great place to upload a video and ask for feedback. The video size is 8 megabytes and it's pretty difficult to make anything as long as 60 seconds and trim it down to that size.
It is probably easier to upload an instagram reel or tik tok or youtube short and just drop off a link in a text chat channel and ask for commentary there. Of course your video is then about as Public as it could possibly be, because the entire world can see it on those platforms-- the exception being youtube where at least you can make your video "unlisted" instead of public. But, these days, maybe everyone is okay with everything being public.
My feeling is Discord would be better suited to doing either live demos or as a guided practice based around each of Tomo's Leavitt videos.
As a live demo platform it would be sort of like a good old-fashioned "recital". Go to a audio/video channel at some appointed time and perform your piece live and wait for a flurry of accolades and good job stickers! Of course to get feedback (and stickers!) you'd have to schedule a time and notify your audience of Tomo Guitar Wisdom peers. Suddenly it's like you're at work trying to herd cats... err, I mean schedule a meeting. People would have to commit to visiting the Discord regularly and often.
However, I'm guessing not many people here are burdened with an excess of free time (or retired old codgers like me) and can drop everything and go watch a performance or demo any time of day or night. Or hang around, lurking in an app, waiting to chat with other guitar geeks.
I think it would actually be better suited for treating each of the Leavitt videos like a classroom session.
There could be one voice/video channel and one text chat channel for each of Tomo's Leavitt videos. And there are LOTS of them!
A player working through the pages for, say, the first duet for Sea to Sea, could go check out the text chat, see how many others have worked through it, see if anyone is stuck on it, ask something about it, and announce the intention to work through it. When you completed it, you come back and say, hey, I did it, or say, dang, I'm stuck, I can read single notes, but not 3 notes at a time ... or whatever the hang-up is.
You could then go to the voice/video channel for that video and see if anyone is in there. This is where it could be interesting.
You could ask someone to play it for you. You could share the lesson video of Tomo playing it and all watch it together, sort of like a watch party, only everyone is playing along (on mute of course!) After the video is done you can all hang around like you're on Zoom and talk about it and decide if you're good with it or you have to go practice it 10 more times on your own, or whatever.
This still will require savvy Discord users. Like, maybe, actual Berklee students.
Further, Discord has the capability to provide intelligent agents. Maybe there could be an agent, or "bot" as they're known, that will start playing the video as soon as 2 or more people enter a video channel. Maybe there could be an agent that can make it easy to schedule a watch / play-along party. Maybe there could be bot for a weekly planner or todo list.
This would require savvy Discord administrators or power users to set all this up in the server. Maybe even... a dreaded "management team". All I know is I don't know how to do it, I just watched a few of the youtube videos that the smart kids post about how cool Discord is.
Anyway, this is already a long and rambling post. My takeaway is that it's like Slack. If anybody is a Slack guru at work or school , they can probably become a Discord guru pretty quickly. Like all software tools, it's very flexible, so lots of users have to commit to using it in order to find a good way make it a productive tool that leads to more practice and better study performance and not just an extra time suck, you know, like TikTok! (or Slack) :)
And with all that said. If Guitar Wisdom itself had a way to schedule a Watch and Play Party with live chat for the existing videos here on vimeo -- and if I could cast them onto my big screen living room TV, that would be more than enough team collaboration for me! Much simpler! Less like going to work.
