'Tis a string that fires no bolts;
'Tis a string shooting no arrows.
'Tis a string that makes no tune;
'Tis a string patching no holes.

'Tis a string that expects no answer;
'Tis a string that is always straight.
'Tis a string that covers nothing;
'Tis a string that holds little weight.

'Tis a problem that you cannot solve?

No. Try.
