During the pandemic we had to do online and it was just awful for music. (Even worse for PE lol). If it's 1-on-1, or perhaps an adult with some musical experience, there's some element to it that could work, but there's no way, for example, to properly fix a kid's posture or fingering positions, or any of the acute details without being hands-on. When you have 10 guitar students in a single class, it's even more impossible!
I much prefer in-person. Music theory though? I could see myself enjoying that online!
My music tech class has 17 students which might not sound like a lot compared to, say, a full literature class of 30 kids, but in context, it's pretty damn challenging - they all need microphones and recording gear, space in the room for performance and all need silence. All need computers with battery power... it's a challenge but a fun one
AHaHA looks like you are gonna have a busy year hahahahah🤣
