Hey Aaron, thanks so much for the kind words!
The number of hours can vary quite a bit depending on the complexity of the song. For the most part, I'll take a few weeks to learn, prepare, and practice the song before I get in front of the cameras. The actual filming of a tutorial generally takes a half a day, but sometimes can take a full day.
After filming, it gets handed off to a video editor and a transcriber, at which point I'm out of the loop - so I have no idea how long all that takes!! Overall, it is quite an involved process!
Cheers!
Mike
Keep rockin!
