I completed the 30 Day Beginner Course with Jonathan Estabrooks. I enjoyed the course but feel that my singing still needs an incredible amount of work.

What should I do next? Should I just repeat the course?

I currently play in a band. My goals are to sing well enough (without be laughed at)

• to convey the vocal melody (I have in mind) for a few of my originals
• sing a little backup
• perhaps one day be good enough to sing one of my originals

Essentially, I just want my voice to be bearable.  I would be thrilled to sing as well as Ringo Starr. Is it possible to improve that much?

Hi, James! Here's a short video with advice on establishing a daily routine: https://www.youtube.com/watch?v=gwzvDGmHJvQ. Ideally, you'll continue improving by exercising your voice daily and working on songs! You're welcome to explore the other lessons on the site, another instructor's beginner course (like mine), or our YouTube channel for continued education and practice. 

It's definitely possible for you to improve and enjoy your voice. If you feel totally stuck, a private lesson (with a qualified teacher in your area, or one of us) can help!
