Found Andrew Clement (Cello) through his twin brother, Brian (Violin & Viola). 

Andrew has a Masters in Music & is principle Cellist for the Salt Lake Symphony - he teaches in Utah, but has some really GREAT video examples from cello learning books you can just use as reference OR, play-along! 

From different beginner books, scales, double stops, etudes, position pieces, help with vibrato, etc... up to advanced pieces!  

What I love: great front views of both hands & he will play the multiple lines of pieces together.

I can play Cello pieces on my 5-string Viola & 5-string Violin (even with it currently strung low F, C, G, D, A).  Just an octave up.

LOVE Pergolesi's "Nina"! 

Since I always like dark pieces - here's a little piece "Lament", from Book 1 Position Pieces for Cello, Upper Second Position - both lines.

He has some 'Social Distancing: Unaccompanied Retrospective" excerpts he does for fun (he says not perfect), accompanied by his story behind learning it - in the video description. 

Another dark one is from Tchaikovsky's Variations on a Rococo Theme, op. 33 - an excerpt from Variation 6: Andante. 

🤣 Andrew has MUCH lighter music throughout his YT Channel - Christmas Carols, too! 

Anyway, especially if you are a beginner, he may be able to help with a book you might be working through.
