Week and a half completed
Alright. I've completed a week and a half and wanted to give a report. After day 1, I felt like I had been punched in the stomach! Clearly I was out of shape vocally. It has gotten considerably easier, although I keep having to remind myself to take in enough air. Old habits take some time to break.
I would consider myself somewhere between baritone and tenor, with the highest note I would feel comfortable singing live being A4 (5th fret of high E guitar string). One thing I have noticed is that the notes from E to A have gotten a lot easier to sing more lightly, while feeling more relaxed than before. My overall vocal stamina has also improved as certain songs that used to wear me out don't bother me anymore. Also, I've been very aware of periodic tightness (neck especially) and have been able to "reset" or start over without tension.
Not completely there yet, but making good progress. Great program! I'm looking forward to seeing continual progress.
