I am an 'adult male human' and can sing only till the 'A' below the middle C comfortably. It would be great if I can sing up to a whole octave below this. I am in no hurry and am willing to expend time and effort. I just want to know what are the techniques and what amount of work would be involved. Also, I would like to know what is the difference between a false bass and a true bass voice and when to employ which.
