The Lifetimes hitmaker's latest record was released on Friday and wants to evoke feelings of a "nonstop party" for those listening to her new material.
"With this new record going out, the energy that I am hoping to create is celebratory, is freedom. Is freedom to be yourself, freedom to be sweaty, freedom to dance with a stranger," Perry told The Zane Lowe Show on Apple Music 1.
"And what I hope to do with 143 is just a continual, nonstop party. Everyone's invited, doesn't matter who you are, eight to 80 all over the world. And that's the kind of music I wanted to create for that live event. I think I'm having the most fun in my life."
Katy explained that 143 is the first album she has released in her career from a position of personal and professional contentment.
The 39-year-old singer - who has daughter Daisy, four, with her fiance Orlando Bloom  said: "When I was going through One of the Boys, which was, whoa, it was like, oh my God, hold on to this ride."
"And then Teenage Dream and Prism, my personal life was not really working. My professional life was working. And then when Witness shifted everything, it started to come more into balance and then Smile really solidified it."
The Woman's World songstress continued: "And now 143 is a celebration of feeling that wholeness, operating out of that wholeness, which is a space I've never written a record from.
"I've always written a record from defence or not feeling enough or trying to transmute my trauma, whatever that was, and to change it. I always say this is the biggest lie I think artists have ever been sold is that they have to stay in pain in order to create."
