The tone library uses a hardware timer and a timer interrupt to generate a square wave with different frequency, so it works on any digital pin. In my previous comment, I said you can only use PWM pins for the buzzer. NoTone is used to handle malperformance of some Arduinos (Thanks Anthony Pelletier for bringing up this issue) SongSpeed and wait are converted to float type (Thanks Andrew Lalis for catching the bug)
You can remove the paper seal on the buzzer to make it sound better (Thanks Ricardo Moreno for the suggestion) There are a couple of improvements that can be made and have been made with this update: It is recently updated on 2021.03.25, 5 years later. I would appreciate a helpful upvote and an interesting upvote from you on TipStory.

You can test it virtually on my simulated TinkerCAD circuit.
