Plinks - I Hear a Call

My poor, poor neighbours. I'm attempting to play assorted songs by ear. Poked around a few iPad piano apps, but the one with the most friendly keys and effects seems to be Pianist Pro.

PLINK! goes the nugget! PLINKETY PLINK PLINK! if only I remembered how to read sheet music. Then I could subject them to my absolutely atrocious sight-reading. (It was atrocious even back when I could do it.)

And yes, I'm still not playing very fluently. XD 10 years out of practice, no score, and an unfamiliar touchscreen thingie. Must improvezorzorzor!
