Explain

Sonic Pi provides a Ruby-based DSL for musical composition and live performance.

Users can program beats, synths, loops, and samples using code.

It encourages learning programming through music and creativity.

Supports real-time audio output with low latency.

Can be used for both educational and professional musical applications.

Core Features

`play` - plays a note or chord

`sample` - plays audio samples

`sleep` - defines duration between notes

`live_loop` - loops music in real-time

Threading and concurrency for layered compositions

Basic Concepts Overview

Note values (e.g., `:C4`, `:E3`) for pitch

Synths (e.g., `:beep`, `:prophet`) for sound types

Code Quality

Comment live loops and sections

Use meaningful variable names for notes and FX
