Show HN: Calculator Music – play songs with number keys in the browser

I built Calculator Music, a small browser toy for playing songs on a calculator with number notes, autoplay, and practice mode.

     It is here:
     https://calculatormusic.com

     No signup is required. I would love feedback on whether the practice mode makes sense and which songs sound recognizable.

Good job. I’d personally love to be able to compose my own tunes. Multi-channel support would be great as well.

that's pretty fun. may be a app can be a good idea
