I LOVE the Fiddlerman Videos that include an animated score!  🤗

...seems like a wonderful way to possibly invite people into our own personal music world - and I've seen some different & interesting ways to do it!  I KNOW there are folks here who can add their favorite methods, tips, & links (or, help me link to other discussions on the forum). 

How to make sheet music animations (Wolowolowolo) - uses 'DaVinci Resolve', 'Medibang Paint Pro' & 'Cobalt' (warns of some YT mp3 download sites being viruses).  I THINK WE SHOULD BE USING OUR OWN RECORDINGS!  

How I make these transcription videos (Michael Solomon) - this is pretty cool!  He uses musescore, Transcribe!, & Soundslice.  🤔... uses MusicXML file. 

Standard vs Graphic Notation: Which is best? (Kieren) - outside the box!

Stephen Malinowski has his colorful graphic 'Music Animation Machine' - read a little explanation on his techniques & tools! - talked a little about this elsewhere, but here he has links to what he uses to create his animations!
