We are going to spend most of our time in Sonic Pi, which will be our best companion during this journey. It is a free (both as in beer and as in freedom) environment to make sound from text, initially made to introduce kids to coding, but it also works with elders, don't be intimidated!

Once you have downloaded and started Sonic Pi, let's see if it works properly by entering the following text in the main area:

play :C3

This line is an instruction which asks Sonic Pi to play the note :C3 (the 3rd C on a piano). It doesn't do anything for the moment because we haven't asked Sonic Pi to play. To do so, click on the button Run on the top left corner, if you hear something, then everything is fine and we can continue!

If this is the first time you write code, congratulations!

We'll often have to click on this Run button, it's a bit fastidious and it is easier to use the shortcut, which you can know by highlighting with your cursor the button. Also, if like me, bright colors attack your retina, by going into the preferences (the Prefs button on the top right corner), and by ticking Dark Mode, your world will be illuminated.

Welcome to the Matrix Neo.

A last note about Sonic Pi which will be useful, we can start to record what we play via the Rec button, when you press it a second time, a window appears to ask you where to save your work.

In addition to Sonic Pi, we are going to use the following softwares (also free as in beer and as in freedom) which may help to analyze sound:

We aren't going to spend a lot of time detailing their usage in these pages, I'll directly provide screenshots containing meaningful information.
