Show HN: A simple web game to help learn chords and basic
progressions
Hi Hacker News, I've created Chord Nebula, a simple web-based game
designed to help users learn and practice piano chords, basic
progressions, and harmony fundamentals. The game integrates with
MIDI keyboards, allowing you to play chords in real-time and
receive immediate feedback based on the key you choose. GitHub
Repository: https://github.com/yottanami/chord_nebula Live Demo:
https://chords.yottanami.com Requirements: To use Chord Nebula,
you'll need a MIDI keyboard connected to your computer. Current
Status: Chord Nebula is still a simple project. I'm committed to
improving it based on user feedback and would greatly appreciate
any support or contributions from the community. Looking for
Feedback and Collaborators: I'm eager to hear your thoughts on
Chord Nebula! Whether it's suggestions for new features,
improvements, or bug reports, your feedback is invaluable.
Additionally, if you're interested in collaborating to enhance the
game, feel free to reach out or contribute directly via GitHub.
Thanks for taking the time to check out Chord Nebula!

|
| And a lot of the hardware and software are pricey enough that I

|
| You can still absolutely deduce the fundamental with great
| accuracy via an FFT, but the approach is a bit more
| involved. The relevant research area here is called
| 'fundamental frequency estimation'.
|
| For an example of this, you can see this app I built that

| on a bass guitar, which are recognized over the microphone:

|
| Even if you have no interest in music, get one. MIDI is
| super easy to read, you can DIY something like an Elgato

|
| This is the best advice I was given. People are always asking
| for you to unfocus and disperse.
|
| Most people that is serious about learning chords have a MIDI
| device. It will make your life way harder to add non MIDI
| devices and the people that will use it are not really that
| committed. MIDI devices are so cheap today that anyone that
| wants one could get one.
|
| BTW I have several MIDI devices because I create my own games
| too.

|
| Related question: Some people are suggesting keyboards that are

|
| I made an app to help learn chords and keys too:

|
| Mine doesn't require MIDI (although it supports MIDI out as an
| option), but I can see why you went with that for yours.
|
| Some notes/thoughts: 1. It didn't work on my iPhone (either with
| Firefox or Safari). 2. A helpful sentence or two would be useful.
| For example, it wasn't obvious that what you were looking for was
| midi in and not midi out. 3. Ignore the folks on here talking
| about monetization (it won't compete with something like
| Melodics). You made a fun little thing and that's great.

| Congrats on launching, and good luck with the next steps.
