None. Tone deaf and can't hold a tune. But I do enjoy listening, and to those of you who CAN play... Thank you!
But your question reminds me of a story:
On our way home after a long day, we didn't feel like making dinner. We also didn't want a drawn-out sit-down meal, or fast food. We found a small local restaurant where we knew we could get a quick burger or some similar comfort food.
The place was surprisingly crowded. There was one table, a high-top deuce (two-seater) near a small area that was apparently used for a stage. It was mid-week and early, so we didn't expect entertainment.
Here's where this story ties in with the subject of this thread:
We didn't really notice that people were bringing in instruments until the second time someone asked "what instrument do you play?"
Turns out it was a an informal open-mike night for local musicians. They all came here on a Tuesday night and just sort of randomly took turns jamming.
Now remember, we just wanted a quick burger and then to head home after a long day. But it would be rude just get up and walk out on a performance. Especially from the table right in front of the stage, with all the other musicians sitting behind us.
We were an audience of two, surrounded by performers.
We soon forgot all about wanting to get home. We were having a great time! It was a memorable night.
