A five finger exercise. 

No significant edits - I noticed that there was a change of time and made it a bit more explicit in the last line

3 Verses, each of 5 lines, rhyming A-B-A-B-C. But the same five rhymes are used throughout, but alternated. So verse 2 goes B-A-B-A-C, while verse 3 returns to the same pattern as verse 1.

I talked about 5 finger exercises being there to expand your skills, just as they do on piano. Keeping the rhyme going was a challenge.
