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.

An algorithmic audio landscape2024 · ambient.garden · ▲193This is an web audio experiment I've been wanting to do for a long time. Basically an ambient music composition, but all the sound elements are laid out in space, and that musical space can be explored freely. It's definitely inspired by in-world music that sometimes appears in games. I basically took that concept, keeping the music aspect, and dropping the entire "game" aspect. I also turned it into a more "traditional" non-interactive album, but since I started with code, why not program the whole thing? Had a blast making the entire album from code, the complete source for the album is…
- SASwaraNotebook – a notation editor for Indian classical music2023 · swaranotebook.com · ▲105
As an enthusiast of Indian classical music, I needed to write music notations in the traditional typeset format. When I didn't find any existing editors, I developed a Swara Notebook, a mobile focused web app to write North Indian Classical (Hindustani) music notations. The notes (called Sargam, similar to Solfege) can be written in English, Devnagri and Bangla scripts. The transcribed song can be played back in 6 different rhythmic cycles (Taal) to the accompaniment of the Tabla(a type of drum) or a metronome. Here's an example of a transcribed song…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

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
