Sonic Pi was created by Sam Aaron. A bit of history now, if you have not heard of him, he, together with Johnathan Graham, was Meta-eX. They performed live coding music. Besides that, they also did tech talks to promote coding and music to different groups of people. Do checkout their performances, talks and also music at the Meta-eX website.
Playing with Sonic Pi
Now, back to Sonic Pi. As I was saying, I played with it these past few weeks over the weekend. After going through the tutorials and examples, I started making music with it.
Here is a glimpse on how to play sound using Sonic Pi.
Do note, if you do not know, the
# character is for code commenting or remarks.
# To make a sound or play a note play 70 # or play :C4 # This plays the middle "C" note. # To play, for example, the C chord play 60 play 64 play 67 # or play chord(:C, :major) # To play sound continously, or in a loop loop do play :C4 sleep 1 end
Sonic Pi also has a number of
fx and samples you can play with.
To hear how Sonic Pi sounds like, go to the website and scroll down to “Music. Code. Simple” section. There you can click on the big “Play” button to listen to sounds generated from the code on the left.
My first “Sonic Pi” song was the intro to Guns N’ Roses’ Sweet Child O’ Mine.
You can refer to the source code for this song below, or check-it-out in my github repo.

It sounds a bit rough. But I am still learning. So, all the code above generated that 1 minute or so song.
Sonic Pi is a good platform for everyone, children and adults alike, to learn about music and also writing code. Those who have no experience in writing code can use Sonic Pi to learn the fundamentals of software development e.g. code blocks, iterations, conditionals, functions, variables, etc. These are covered also in the “Help” section – “5. Programming Structures”.
Go ahead. Download and install Sonic Pi. It supports Windows, Linux, Mac OS, and Raspberry Pi.
