I've been taking classes for one year when I was in uni, about 15 years ago. I have always had the problem that I would run out of voice after 1-2 songs. My teacher at the time kept saying my problem was that I had to strengthen and use the diaphragm, which I did but only made little progress. Eventually, since every class felt like defeat, I gave up. Did I just not train enough? Likely. Do you have any advice to share?
