My mother is a musician, who also teaches singing and piano. Her pupils encompass keen singers and players of all ages and most abilities, and every January she hosts a musical evening so they can all perform to a sympathetic audience.

It is quite an occasion, with wine and a buffet to follow the performances. Honour dictates that each year Christian and I also must turn up, dust off our violins and scrape our way through a duet in front of a crowd some of whom remember us when we were in short trousers.

I usually produce a poster for the front door, generally with something cribbed from Google images and a Shakespearean font that I downloaded a few years ago. This year I decided to illustrate it. I fixed my mind’s eye on a vision of my brother playing his violin with my mum accompanying on the piano, and put pen to paper.
