"I'm singing what I want to sing based on the emotion of what that day feels like. That's what comes out of my mouth and guitar. That impacts people. They know anything can happen"

In this quote, John Mayer is emphasizing the spontaneity and credibility of musical expression, suggesting that the art of songwriting and performance is deeply intertwined with the emotional state of the artist at any given minute. He highlights the concept that music is not a fixed or premeditated procedure, but rather a vibrant and fluid kind of expression that progresses with the artist's sensations and experiences.

Mayer starts by asserting the flexibility and individual nature of his music: "I'm singing what I wish to sing based on the emotion of what that day seems like." Here, he highlights the importance of staying true to one's genuine emotion, allowing it to guide the creative procedure. This technique suggests that instead of adhering to a fixed setlist or formula, Mayer chooses to let his existing state of mind and experiences shape the instructions of his music. This approach highlights authenticity, which is frequently considered a powerful and relatable aspect of art.

The next part of the quote, "That's what comes out of my mouth and guitar," even more highlights the organic and instinctive nature of this process. By juxtaposing "mouth" and "guitar," Mayer acknowledges the double channels through which he communicates his feelings-- vocally and instrumentally. This pairing recommends that both lyrics and musical structure are important to revealing his feelings.

Lastly, Mayer mentions the impact this spontaneous approach has on his audience: "That affects people. They know anything can occur." This exposes a reciprocal relationship between artist and audience, where the unpredictability and raw sincerity of his performances cultivate a sense of connection and enjoyment. The audience, sensing the genuine emotion and unpredictability, ends up being more engaged and open to experiencing something special and powerful in each efficiency. Basically, Mayer champions an artistic process that is both deeply individual and generally resonant, where credibility and emotional reality end up being the bridge between artist and listener.
