DIPHTHONGS


*A diphthong is a combination vowel- two vowels sounds in succession in the same syllable, with no consonant between.
*The basic rule in singing diphthongs is that the two component vowels are of unequal length. 
*The longer of the two vowels is called the sustaining vowel.  It ordinarily occupies almost the entire time of the diphthong. 
*The other component is the vanishing vowel, which occupies as little as possible of the total time. 


Look at the words below.  Say them to yourself.  Notice how each word has two distinctive vowel sounds.  The vowel sound that is underlined is the sustaining vowel.  When singing this vowel, it should sound almost the entire duration of the note.  The vowel sound in parenthesis is the vanishing vowel.   When singing this vowel you should sing it for the shortest duration possible.

Way = EH + (EE)
Now = AH + (OO)
Joy = AW + (EE)



The chart below shows the five basic diphthong combinations:
     The underlined vowel = sustaining vowel
     The vowel in parenthesis = vanishing vowel
