ÆTHRA – Writing Music as Code
Hi HN I’m building ÆTHRA — a programming language designed specifically for composing music and emotional soundscapes. Instead of focusing on general-purpose programming, ÆTHRA is a pure DSL where code directly represents musical intent: tempo, mood, chords, progression, dynamics, and instruments. The goal is to make music composition feel closer to writing a story or emotion, rather than manipulating low-level audio APIs. Key ideas: - Text-based music composition - Chords and progressions as first-class concepts - Time, tempo, and structure handled by the language - Designed for ambient,…
In plain words
ÆTHRA is a domain-specific programming language for composing music through code rather than traditional audio software. It treats musical elements like chords, progressions, tempo, and dynamics as first-class language concepts, allowing composers to write music as text that directly expresses emotional intent. Designed for ambient, cinematic, and minimal music, ÆTHRA is built on .NET and aims to make composition feel like storytelling rather than manipulating low-level audio APIs.

Hi HN I’m building ÆTHRA — a programming language designed specifically for composing music and emotional soundscapes. Instead of focusing on general-purpose programming, ÆTHRA is a pure DSL where code directly represents musical intent: tempo, mood, chords, progression, dynamics, and instruments. The goal is to make music composition feel closer to writing a story or emotion, rather than manipulating low-level audio APIs. Key ideas: - Text-based music composition - Chords and progressions as first-class concepts - Time, tempo, and structure handled by the language - Designed for ambient, cinematic, emotional, and minimal music - Interpreter written in C# (.NET) Example ÆTHRA code (simplified): tempo 60 instrument guitar chord Am for 4 chord F for 4 chord C for 4 chord G for 4 This generates a slow, melancholic progression suitable for ambient or cinematic scenes. ÆTHRA currently: - Generates WAV audio - Supports notes, chords, tempo, duration, velocity - Uses a simple interpreter (no external DAWs or MIDI tools) - Is intentionally minimal and readable What it is NOT: - Not a DAW replacement - Not MIDI-focused Why I made it: I wanted a language where music is the primary output — not an afterthought. Something between code, emotion, and sound design. The project is open-source and early-stage (v0.8). I’m mainly looking for: - Feedback on the language design - Ideas for musical features worth adding - Thoughts from people into PL design, audio, or generative art Repo: <https://github.com/TanmayCzax/AETHRA> Thanks for reading — happy to answer questions or discuss ideas.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
