Somebody having been much troubled to learn the keys of the piano forte, proposed the following lines as an alleviation of the labor:
HOW TO LEARN THE PIANO KEYS IN A QUARTER OF AN HOUR.
All the G and A keys
Are between the black threes.
And ‘tween the twos are all the D’s.
Then on the right side of the threes
Will be found the B’s and C’s;
But on the left side of the threes
Are all the F’s and all the G’s.
Watertown Chronicle (Watertown, Wisconsin) Apr 23, 1851
