Get on Instagram

A lot of people log their violin playing there.  I think you can post videos of any length there, now.  You should also load it to YouTube, but if you want more views perhaps try Instagram, on top of YouTube.

A great way to get ahead...

...some YouTube videos can be pretty nifty, I know like showing the fingering for 3 octave scales and where to shift to different positions.  I also came across some good exercises to do with finding notes shifting, as well, from an adult beginner violinist.  She showed us and linked us to exercises.  Not all videos are quite that magical, but I've enjoyed beginning my sojourn/search.  I just save the links in a playlist on my YouTube channel, you can also make it private.  I've had 5 violin teachers and stopped to teach myself, so I'm grateful for this.  I'm sure the teachers on YouTube are grateful, as well, as they get "a good turnout."

If you search YouTube...

...there are plenty of adult beginner violinists.  You can make multiple YouTube channels on your Google account.

I've run across other countries, like the Netherlands and Norway.
