It would be cool if Jamie could comment on this because I'm mostly following the principles in his book on this recordingin, or trying to. Jamie, any comments? No pressure, by the way ;)

The link expired so I put a new one here:

I know that I'm doing something wrong and this is a "comped" track from many vocal takes, where I compared the lines from the several takes and chose the best one, just like is being done in the studio, so in a way this clip is a bit misleading - I've taken the biggest mistakes out. But since I'm mostly using the principles from the RYV book, it would be cool to hear if Jamie can spot what I'm doing wrong.

I like it! Especially the grit. Overall, it sounded pretty darn good. I couldn't tell that you were recovering from a cold at all!
I've got a few covers on this board, if you've got the time, could you give me your opinion on them?
Keep singing! You're already good, and you're gonna get even better.

Think it sounds cool. Why do you think you are doing something wrong? Does it hurt? Does it feel funny? As long as it doesn't hurt and it sounds cool, that's all we care about:) Good job;)Grit sounds good, just make sure its in your palate. You'll get to know your voice better and better as you keep singing. If for some reason in the future you still think you are doing something wrong, you can always book a lesson and we can discuss, but honestly, I think it sounded okay. heard a couple little spots, but nothing serious;)

I think my problem is mostly vocal stamina. I can sing like this for only a short while. Sometimes I start to get extremely tired after just a minute of singing like this. Any good tips to build up stamina? I'm assuming that I just need to work out my voice longer than I do, at least an hour per day? When can I expect the stamina to improve?

You can expect the stamina to improve when you really dedicate yourself to singing every day. I myself ama lazy singer, because I all I have done for the past 16 years is teach teach teach with an occasional band. However that has all changed with the workshops around the world coming up and some other big gigs that I cannot really talk about yet. So, every day, I have over 2 hours of music I am singing from various artists, and it is the ONLY way to build stamina. Exercises only build the instrument, stamina comes from using that instrument;)

Jaime, exactly how do the Isolation exercises and scales help build the voice? Wouldn't just singing all day help you improve?
