Experimental Poetry Form: filter

Today’s experimental poetry form is called filter.

In the form, there are two stanzas.  Each stanza has three lines.  Each line has five words.

In the first stanza, each word must contain the letter “a”.  In the second stanza, none of the words can contain the letter “a”.  The idea is that the letter “a” was “filtered out” between the first and the second stanza.

Here is an example poem using the form:

Many emails arrive each day.
Communication has acquired great ease.
Substantial contemplation has apparently disappeared.

Letters used to be costly.
Thought with effort were there.
Words needed to signify something.
