but for all I aspire I am really a liar
No more misplacing your keys!
I wonder, can you re-lock it the same way?

No more misplacing keys, but this spells doom for the rythmically challenged.

This is so cool. Security would be enhanced by having at least one more detector in a different location, so as to divide the door in sections where the sequence would depend not only on rhythm but on which half, third,
fourth, etc. of the door each note was knocked. So you would have to see the door being unlocked in order to steal the sequence, not just hear.

Is actually an INTJ
That's brilliant.
I would trust a key or a number more though.
And what happens if the battery goes flat?
actually it would be even better to take this design and alter it to be controlled by a tune being whistled instead

The same thing that happens if it falls off.
(of course I'm assuming it's not firmly attached to the handle in some way)
Another innovation would be to have the door become powerfully electrified for a period if several incorrect knocks are given, otherwise someone will build a KnockCracker^TM and decode your LockKnock^TM by rapid trial-&-error.

I imagine if the device ever went commercial it'd be marketed as an emergency fallback in the event of keys being lost/locked inside.
When the device had been explained, I knew he would use the knock he did at first. It's like 1234 as the default PIN for a safe. That knock is instantly recognizable, though I've no idea why. The earliest I remember having heard it was on a TV show about a hand puppet called "Sooty".
