But now with pricking pins of steel,
Those same vibrations come from turn of wheel,
When in dents lightly made on a disc,
Which around and around we playfully whisk;
The pin points strike in and then out,
As the thing is whirled about;
And, by magnifying the scratching it makes
The picture of the whole sound action it takes;
And reproduces the vibrations on our ear,
Of an opera or any piece we wish to hear.
