Are there any good online singing courses?

[Crosswind]

For a guitarist who is hoping to learn to sing but cannot afford regular singing lessons, are there any good online courses out there that do a good job of teaching singing?

You might have a look on Udemy. I've found a number of guitar, piano, and recording courses to be really helpful. But wait for sales (which they have a lot).

I can recommend Ken Tamplin

There's tons of free content there, and he sells a not-cheap structured course. I bought it several years ago and while I did not pursue it all the way through--apartment living, thin walls--I gained many helpful tips. Those that I had been aware of in past years and simply forgot tracked with my vocal instruction in a world-class university choir I belonged to. (Carnegie Hall, Andre Previn engagement, etc.)

He updated the course he sells fairly recently. I haven't explored that one since I have plenty to work on as is. Oh, and personalities strike people in different, subjective ways, but I find him very engaging.
