Hey I just started on Muris's Legato lesson and have become pretty fascinated with the legato technique. I was just wondering what are the main components to creating a sweet legato run? Is it just taking various scale boxes and combining the notes that you want?

Basically, I think it can be anything you want, if it sounds good to you then it's good

Just like that,you take boxes and make combinations you like.
Add some slides to connect boxes,even some string skipping,sounds nice.

appreciate the help and love the lessons Muris!

You're welcome,keep exploring!
