Which beginer course is best for me

Hi There

I have played guitar for over 20 years and had never attemepted to sing other than karaoke but for profesional reasons i want to learn how. when reviewing the three beginer courses im confused as to which one is best for a complete beginer like myself. the first is from  Camile who is great but i heard somewhere that if your a male then its best to get lessons from  another male due to range so i figured my options are the two remaining lessons but can anyone steer me in the right direction. my genre is rock and blues if this helps

Hi Lee,

It may be more fitting for you if you follow along with the two male singers, but it's up to you. Regardless of which you choose, you can always jump out and go into one of the other courses. 

good
