To chatter, to clack Dr Pusey thinks it is derived from Paternoster (the Lord's Prayer) The priest recited it in a low, mumbling voice till he came to the words, and lead us not into temptation, which he spoke aloud, and the choir responded, but deliver us from evil In our reformed Prayer Book, the priest is directed to say the whole prayer with a loud voice Probably the pattering of rain- i e the rain coming with its pit-pat, is after all the better derivation Gipsy talk is so called from the French patois (See Patavinity )
The things you say while you're doing a magic trick Sometimes it is a story, or makes the audience believe something that helps fool them A form of misdirection

If something patters on a surface, it hits it quickly several times, making quiet, tapping sounds. Rain pattered gently outside, dripping on to the roof from the pines
