Hello, so I have a couple of questions on what my daily practice routine should look like. When I want to start practicing in a day, what should I do before I watch the lesson for the day?

After I watch the lesson, what should I do after watching the lesson?

I see a lot of daily warm up routines lessons that you guys posted. My question about is do I have to do all the lessons again everyday? Isn't there a condensed audio recording or something that can be used for this instead of visiting each lesson again?

Hello! 
Many tutorials have a short warmup built in, after the intro video. But for those that don't, you can use a warmup from any tutorial classified as a "daily routine" or "warmup".
The general idea is: warm up your voice before working on a new skill or working on a song. You don't need to spend a ton of time on your warmup alone; how much time you spend singing in total is up to you! 

My recommendation is: stretch, breathe, and gently warm up (ideally on a lip trill, MUM, NG, etc). Then watch a lesson video to work on a new skill, do some ear training, or work on learning & rehearsing a song.   Really, it depends on your goals and how much time you have to spend.

I'll find out about an mp3 for you! 

Thank you!
