A card for my Father.

He turns 70 soon, but as my parents are in Australia, I will be unable to see them. He is a musician, so I have ordered him a recording device from a local supplier over there. And I sent this card to him, to encourage him to use it when it gets there. :D

Cabers are not known for their musical abilities. But I imagine that they would get pleasure from trying.
They certainly appreciate many kinds of human music!

This stringed instrument has three primary strings, with two finer strings of a higher octave pitch, flanking the outer pair. The middle string is the lowest. It is good for twiddling, twanging, strumming, plunking, and ‘wauling to. (At least, that’s what I was considering at the time. ;) )
