Warming up

Hello! 

I am at the lesson 3 and i wanna know something about warming up .

The warm ups from  daily routine day 2  have just few semitones . Is that enough for us untill we finish the 30 days course ? I mean , like 4-5 semitones are enough  , or is just an demostration and i need  to  do more than that ? 

P S. When i go  more than C4 in my chest voice as  example , my voice go a little bit shaky  , like my  sustaining is  not that good  in this  moment.

What i am supposed to do ? just few semitones or more than that ? 

Hi, Daniel! 
Ideally, your warmup should cover your full range. Which beginner course are you following? 
If you're starting to strain around C4, you should let your voice flip into head voice! I like to use the lip trill in tricky areas to determine which register is most comfortable if you're not sure whether you should be in chest or head voice.

Ok, i understood   what transition  i need to  make . I am using thé Jonathan's course but,  i want to know how to do the whole range. Where  am i supposed to do ? Because here on the course its not  the whole octave or a range. They are like 4-5 semitones.

 P.S. Should i do any video the whole octave or The same  thing like in videos.(for the rest of  exercices) 

Gotcha. If you're able to keep going up or down, then yes, do that! The only exercises that should have a more limited range would be ones focusing on a specific register (like a chest voice only or falsetto only exercise). 

Any of the warmups on this page should have a wide range: https://www.30daysinger.com/warmups

And my beginner course does as well, if you want to check that out! I usually recommend beginning guy singers use Jonathan's course so they can hear examples in a guy range, but I do play the lower octave (or the bass note) for guy singers in my course. Up to you!
