Double Bass
A double bass is a funny, old instrument.
It looks like a missile with a strange warhead.
Its curves are like snakes frozen by ice.
It has a big fat belly like a hot-air balloon.
When you bow it, it sounds like something heavy rolling along the ground.
But when you pluck it, it's more like a grumpy' old grandfather.
Yes, the double bass is a funny, old instrument!
