I recently met a lady who was a violinist and it reminded me of the idiom, or proverb if you prefer, it's always good to have a second string to your bow.
This idiom means that it's always useful to have more than one skill so that you have some options, particularly in difficult times.
The most famous English violinist, and someone that I admire for his individuality, is Nigel Kennedy. He doesn't do part-time brick laying but he certainly applies his musical talents to many different types of music. Like me and Count Bassie, he believes that there are only two types of music; good and bad.
Here are two film clips; one when he was interviewed, still quite young and playing his signature tune, Vivaldi's Four Seasons and secondly, playing Hendrix with some Polish friends.
