It’s Friday afternoon at the Apple store and, like almost any time at any Apple store, it’s bustling. On the second floor of the World Trade Center location, the shiny white interior matching that of the space-age mall in which it lives, people are swarming — moving around the tables, occasionally sitting, and getting help with their most pressing i-questions. At one table though, the 10 or so gathered around are quiet. Headphones on, they’re experimenting with creating their own music on GarageBand, instructed not only by Apple employees but also by a special video guest: Florence and the Machine’s Florence Welch. It’s part of a new Today at Apple Music Lab starring the Grammy-nominated singer/songwriter, who takes you through her somewhat unorthodox creative process. Filmed in the same studio where her new album High as Hope was recorded, Florence bangs on the floor and plays a few notes on the piano, explaining how she finds inspiration and puts together the sweeping, orchestral music she’s known for without any formal musical training.

The music lab, one of the free Today at Apple sessions available at every Apple store, walks users through how to use GarageBand's various tools, teaching them how to create their own percussive base using the beat sequencer, make use of the world around them with the sampler, and recreate the sounds of instruments they may not even know how to play using smart instruments. And you don't even need a musical background to make the most of it.

We got to catch up with Florence over the phone as she tours the world for her new album High as Hope. Read on for her thoughts on working with Apple, how she writes her most personal lyrics, and why she keeps deleting Instagram.

Teen Vogue: Tell us about how your partnership with Apple and the Music Lab came about and why you decided to undertake this.

Florence Welch: I guess because I'm a shy person and I've also quite liked the armor of people not knowing whether it was a band, or whether it was a solo project. I like being able to hide behind the mysteriousness of it. But I thought it was a nice way to be like, no, I make the music too. To show people the process, however rudimentary my process is, and it's pretty rudimentary.

[Apple] asked and they were doing this thing, and I saw some other examples of other artists doing it, and I just though it was really interesting. I thought it was actually a really nice way of showing the process. I was just flattered as well because I think I, as someone who is not a trained musician, I do things instinctively. I was excited about the idea of maybe, through this Music Lab, showing people who perhaps didn't feel like they were trained enough or didn't have technical knowledge that they could. Just to make things. Regardless whether you feel like you're highly skilled, it's fun, and you can. It's possible.

TV: Were there any favorite parts that you have of what you filmed or what you did for the music lab?

FW: It was a really nice day, really, because we did it with Vincent Haycock, who I've collaborated with ... we made a little film together for How Big, How Blue. And we did it at Emile Haynie's house, which is also the studio where we made High as Hope. So it was really, it felt very natural, and actually it was really nice with the two people that have been a good part of my creative process, to sit down and unpack it all.
