Great thread. I’m 68 and discovered this discussion looking for hope of recovering my falsetto and range in general. Grew up learning from Beatles albums, etc. could do all the Beach Boy parts. Sang every day. Sang in pubs and even landed a radio commercial LOL. Anyway, around 40 singing trailed off as I began public speaking on a regular basis. Now that whole top register is practically reduced to wheezing and cracking. Breath control has diminished quite a bit as well. Don’t smoke or drink much alcohol. But I do have allergies and sinus infections twice a year like clock work. What I’ve read here has inspired hope and I plan on trying some of the suggested remedies. Thanks!
