Singing exercises - Pronunciation

To improve on my pronunciation when singing i find that tongue twisters help.

A few tongue twisters that i have found are:

"Unique new york"

"Flash message"

"Good blood, bad blood"

i find that the shorter tongue twisters are more effective to use for pronunciation as they can be sung quickly going up or down the scale.
To show that these tongue twisters are helping to improvpe my pronunciation i shall video myself trying them out to show my progression and improvements.
