I played a B
When a musician plays a wrong note and acts like it was totally normal and not a big deal.
'I played a B' he said, like it was the most normal thing in the world and no one had heard the wrong note.
'I played a B' she said, while the drummer was still laughing at her from the back.
'I played a B' he said, as if the audience had been expecting it and it was just a regular day at the concert.
