Sonic pi is an open-source programming environment designed to explore and teach programming concepts by creating sound production music processes. The Code executed by sonic pi is based on Ruby, which is a beautiful and concise programming language. This means that you can write a lot of code without having to worry too much about syntax and braces-though important for complex programs. 1. Getting Started
