I was having a meal in a smart Spanish restaurant here in West Bridgford, Nottingham, with eight other people. The food and drinks were excellent (and pretty expensive). This was a classy place.
But in the background - constantly - there came the sound over loudspeakers of 'music'. The recording did not seem to be of music played on musical instruments by real musicians. I guess it was computer-generated. It sounded like this:
I apologize if you are saying 'What has this to do with traditional jazz?' Nothing really. I just wanted to get it off my chest.
However, if you would like to hear something relevant to jazz and the topic of 'background music', I can tell you I had an email from a clarinet-player about how disheartening it is to be booked to play at a venue where you find the audience consists of a large number of noisy people who are more interested in the football match being shown on the large TV screen at the back of the hall than in your music.
I expect we have all experienced such a gig from time to time. You have to try to keep your spirits up. If nobody is taking any notice of your music and it is being treated merely as a 'background noise', regard the gig as an opportunity to try things out and rehearse some new tunes.
