Playing music in the street or another public place for voluntary donations is known as busking. Musicians often say this is the best musical education you can get because convincing a tough New York crowd to donate forces you to elevate your skill. A good busker may be able to earn more than they could in more traditional jobs. According to money.com they can earn anywhere from nothing to more than $30 per hour depending on many things, not least of which are talent and traffic.
