Street Piano Dr. K is Brendan Kavanagh. Also known as Dr. K, is a British pianist and piano teacher. He specializes in playing and improvising, often combining classical, jazz, blues, rock and traditional Irish music. He often plays the piano in various public places at train stations or on the streets. Sometimes he invites friends to perform duets, or joins in other people's performances impromptu.

When I watched Dr. K’s video for the first time, I realized that this man has been doing this at the airport piano for a long time. He uses clothing and other external things to combine with art to create some contrast. The music is improvised. This pianist often appears in the subway, shopping malls, and airports. He often pretends to be a beginner and chats up piano players, and then they play piano music together. What a low-key, warm-hearted, and loving British pianist.

Music is the most universal language in the world. Even if there is a language barrier, people can communicate without any barriers through music. The performer can integrate his own emotions into the music and convey it to the audience. The audience can also feel the performer's emotions in the music. When the performer is happy, the audience will be happy too. When they are sad, silent listening is the best comfort.

In music, you can feel the most original and sincere kindness of people. Even if it’s just the time of one song, it might be enough.
