I had tried it briefly because my favorite youtube violin teacher Beth Blackerby recommended it in one of her videos, and it's great. But, I wanted the experience of coding something myself (I'm retired, hadn't coded in four years, lockdown has made me antsy) and I wanted something that was a standalone single HTML file, and I wanted something that felt easier. So, I ignore the time dimension and paint the notes on the staff the way a player is used to reading them rather than Intonia's interface which looks more technical.
