Write lead sheets in a Markdown way and transpose in a second
Hey HN, I'm a software engineer with a passion for playing guitar. (https://ivanhsu.co) In the software industry, we use clever plain-text syntaxes like Markdown and Mermaid to handle complex layouts. This lets us focus on the content itself and quickly produce beautifully formatted documents. Isn't sheet music and chord charts just another form of documentation in the world of music? That's why I created Cord Land https://cord.land/landing ! It's a website where you can quickly generate lead sheets and draw chord charts using plain text. Even better, it can…
In plain words
Cord Land is a web tool for guitarists to write lead sheets and chord charts using plain-text Markdown-style syntax called Corduroy. It automatically transposes songs between any of the twelve musical keys instantly. Designed for musicians who want to focus on content rather than formatting, it combines software engineering practices with music documentation, allowing users to quickly generate and customize chord charts and lead sheets without complex music notation software.

Hey HN, I'm a software engineer with a passion for playing guitar. (https://ivanhsu.co) In the software industry, we use clever plain-text syntaxes like Markdown and Mermaid to handle complex layouts. This lets us focus on the content itself and quickly produce beautifully formatted documents. Isn't sheet music and chord charts just another form of documentation in the world of music? That's why I created Cord Land https://cord.land/landing ! It's a website where you can quickly generate lead sheets and draw chord charts using plain text. Even better, it can automatically transpose songs! Just write in one key, and it can be instantly converted it to any of the other 11 keys you want. I've implemented a new syntax called Corduroy, an extension of ChordPro syntax specifically designed for guitarists. Besides showing chord names above lyrics, you can also customize chord charts. For example, `%x32o1o%` will automatically draw a C major chord in the first position! Feel free to try it out here: https://cord.land/landing#playground For more usage details, please refer to: https://cord.land/tutorial The name "Cord Land" comes from "Cord" and "Chord" being homophones, representing chords. Let's keep our passion for playing guitar alive, even after work! Ivan Hsu

I built the world's most impractical 1000-pixel display and anyone in the world can draw on it. It draws a single pixel at a time and takes 30-60 minutes to complete a single image. Anyone can participate in the project by voting for the next image to be drawn, and submitting images. https://kilopx.com/

Kitten TTS is an open-source series of tiny and expressive text-to-speech models for on-device applications. We are excited to launch a preview of our smallest model, which is less than 25 MB. This model has 15M parameters. This release supports English text-to-speech applications in eight voices: four male and four female. The model is quantized to int8 + fp16, and it uses onnx for runtime. The model is designed to run literally anywhere eg. raspberry pi, low-end smartphones, wearables, browsers etc. No GPU required! We're releasing this to give early users a sense of the latency and voices…

I was wondering how I can arrange objects along a spherical helix path, and read some articles on it. I ended up learning about parametric equations again, and make this visualization to document what I learned: https://visualrambling.space/moving-objects-in-3d/ feel free to visit and let me know what you think!

For HTML Day 2025 [1], I made a web service that displays the current sky at your approximate location as a CSS gradient. Colours are simulated on-demand using atmospheric absorption and scattering coefficients. Updates every minute, without the use of client-side JavaScript.
