Composing Music 🎵 with an F# Internal DSL

I've been working on an internal DSL in F# that makes it incredibly easy to compose simple music. The goal is to provide a declarative, expressive way to create melodies while handling the underlying sound generation.

Here's an example of composing and playing the Super Mario Bros. theme song using the DSL:

open DSL.Generator
open DSL.MusicBuilder
open DSL.Player

let music = MusicBuilder()

let song =
    music {
        note "E5" 0.5
        note "E5" 0.5
        rest 0.25
        note "E5" 0.5
        rest 0.25
        note "C5" 0.5
        note "E5" 0.5
        rest 0.25
        note "G5" 0.5
        rest 0.25
        note "G4" 0.5
        // ... more notes ...
    }


let songName = "mario_bros_theme.wav"
// Generate a WAV file and play the song
createWav songName song
// play the generated song
playSound songName

With just a few lines, you can define melodies using note names and durations while the DSL takes care of the rest. 🚀

I'm considering extending it with chords, loops, and instrument variations.
