Hiya.

I have noticed as time has gone on and as i have become older that my voice has become stronger, however i used to be able to sing whole songs in falsetto, but now cannot even ACHIEVE/ REACH falsetto!!

have i lost it forever?

so no1 knows?

Sorry, but no, I don't know. My dad is a tenor, nearly 70, and can still sing falsetto, so I don't think it's really a feature of maturing? But not sure how helpful that is.

Have a look here:

There's something on there that looks like it might be relevant, to do with forcing your voice before it's finished developing. I don't know, I've never had any singing training; hope the link's of use though .
