From the way he sings to his laugh, the bluesy crooner's had to adjust.

John Mayer has only sung in public once since having two surgeries on his vocal cords (the most recent in August 2012). The singer-songwriter, known for his distinctive, bluesy warble has come to a conclusion: his voice likely will never be the same.

"Everything changed about my voice," he tells Rolling Stone in a new interview. "I don't have the projection. My laugh changed. The way I used to laugh is kind of like that ‘I'm embarrassed,’ high-pitched laugh. I don't really laugh that way anymore. I've found new ways around everything – new ways to talk, new ways to laugh. Now I wonder if I can go right back to the shape of my voice that I had when I was singing once I can do what I want to do with it."

Earlier this month, Mayer surprised everyone by playing his first set in two years at a benefit for firemen in Bozeman, Montana, where the musician currently lives. The firemen aided Mayer at his house last summer, when a wildfire threatened its destruction.

Mayer moved to Montana after his first throat surgery to recover and has remained on hiatus there ever since. In late 2012 he began dating pop superstar, Katy Perry. When asked how his romance is going, he simply responded by saying, “I'm quite happy. I'm happy in all aspects of my life."

Mayer appears to be moving with less weight on his shoulders nowadays. He spoke about not having any trouble in his private life at all, aside from people "geo-tagging" his whereabouts during nights out on the town him and how his views of the media have matured.

"On the outset of all this stuff in 2007 and 2008, everybody was thinking, ‘Well, what does this mean for me? When somebody takes my picture and they put it up on the Internet the next day and they write stuff about me, what does this mean for me? What is this going to steal from me?’ And I think time has shown that nothing will be stolen from you. It's just a photograph of you and your dumb scarf that you put on because it wouldn't fit in your suitcase. Cool. If you want to ‘style police’ my day off, that's fine."

Mayer hopes to tour soon, and plans on changing up his performance style to something a bit more organic, natural and "palate-cleansing" in the future.
