That this is a TERRIBLE name!
First of all, if you are going to use a common noun as a name, at least spell it right.
Cadence is how it's spelled. Kaydence just looks illiterate.
Cadence doesn't even sound prety: kay-dense. Kay-dintz. Thump, thump. Thud thud.
That's if you enunciate it clearly. Most people don't, and it ends up making a sound straight through the nose.
Also, if using a common noun as a name, the noun itself should at least have a nice meaning:
Hope,
Rose,
Dawn,
Charity.
Cadence just means the rhythm of something, not even necessarily a pleasing rhythm.
