Method: Pick one letter.  Find sounds that feel like the letter, (without the use words or the human voice) and match them to a static text.

Results:  This test fails or is inconclusive at best.  

Conclusion:  .Does this page feel or sound like "Z"?  Where this test fails is in the stated purpose.  The distinction between the various graphemes and phonemes of a letter is not dealt with. 

Graphemes:
          Besides the obvious dual nature of the look of

there are hundreds of fonts,  and hand printed styles so wildly inconsistent as to be illegible or at leas unrecognizable to the beginner. With this DVD we somehow need to address the range of the look of letters in a learn able manner.  

Phonemes: 
          The letter is one of the few letters that have only one sound or one phoneme.  "z iz too eazy". "cent" and "sent" sound the same.  With 26 letters, representing 46 or 48 or more sounds, it gets complicated fast.

"counting the number of  phonemes is like counting the number of colors in a rainbow.....we can identify 36 clear instances of the primary or uncombined phonemes in speech [14 pure vowels, 22 pure consonants]."*  
         
          The animated poem "motorized razors" as a homage to the sound of "z" works, yet many letter combinations are used to get there.   

          Each letter's position within the alphabet, and in the spelling of words and each letter's participation in representing the sounds of the human voice must be addressed, it's complicated but should probably be addressed on each letter's home page.  Back to the drawing board, on this one.
