Silent composer of digital symphonies, tapping out melodies with tactile whispers. A flat orchestra, where fingers dance to summon letters from an unseen world.

I can have a double, a single or a treble, but no bass. For me you can use a hook or a needle, as you’ll find me quite versatile. Start with a loop, a slip or chain, it depends what you have to gain.

It starts with a number That may even match The number of fingers it owns You can find them in roads Or find them in drawers Or ringing out specific tones

Ideally, I’m always running, but never in a race Milk, eggs and cheese love to hang out at my place In supermarkets, in restaurants and in homes I’m used My invention has saved lives, and it’s quite convenient, too

I will bring you up high Your place or your speech But what holds me can break Or release with a screech
