How do you warm up your voice and vocal chords in order to get the best out of your voice when singing?

Try getting vocal lessons---A good teacher can tell you what you need to work on and find warm ups that are good for you. You can try octave slurs for range, long tones for endurance, and tongue twisters to warm up your mouth and diction. Maybe that'll give you a start

i am a singer so i know what to do lol. humming a sweet and low tune helps me a lot, but u can also say one two three four five four three two one. each time you say a number, get a note higher, this helps get your notes in the right range. hope this helps

You should touch bases with all of your instrument before jumping into really practicing or performing. Using scales, warm up the lowest part of your voice moving up to the highest, and then back down again. I usually spend a good 15-20 minutes on this. Be very aware of your breathing as you warm up your voice, making sure that you are taking low, relaxed breaths. A good thing to do while warming up on scales is to mix up the articulations of the notes. Sing some scales with all very stacatto (short) notes and try to sing some scales very legato (the notes very lyrical and connected.) That will help the body kick into gear and start helping your vocal apparatus do what you want it to! =) Hope that helps.

The exercise I usually start with is called the "siren" where you start from the bottom of your range and raise the pitch until you get to the top of your range and then drop it back down to the bottom. It'll sound like a siren. :)
