Show HN: Play music by typing (benzguo.com)

Also, you can make a key stay down by holding down Control (Command on a Mac)

The scales produced by typing along one row reminded me of the castle theme from Super Mario World. If my javascript-foo was greater, I would write a function that types this, but alas.

It'd be cool to integrate my site http://www.soundslice.com/ into this.

Is a shame there are some chords that you can't play (chord: pressing notes at the same time), such as "yup". But I think is a hardware limitation rather than a bug in the JavaScript.

…But I stopped caring when I got to filling in the dictionary of notes, so if somebody else wants to finish it, be my guest! ;]

More music please from the talented among us!

I've tried things like this before, but this is great.

I knew playing all those typing race games would come in handy one day!

I would like to same some kind of feedback, like piano diodes that get on and of for you to follow a tune or tell you when you get wrong.

I would love to hear nonsensical boops as I code.

Also, perfect thing to test my N-key rollover keyboard (which only goes to 6 due to USB limitations...)!

The behavior of cmd as the pedal is a little weird. When you release the pedal, the sound should stop. Maybe it's just a Mac bug, though.

The top row seems to be an octave higher than it should be, that interferes with moveability. Though I understand you probably wanted to expand the range.
