Even those with no musical training will probably disregard your mistakes if the overall performance is good. Example: My favorite Irish traditional duo is Peter Horan and Fred Finn (both RIP, alas). They were legendary for the tightness of their unison playing. There is a great video [1] of them from 1982, when they had been playing together for 25 years. At the 1:05 mark, Peter (the flute player) switches to the next reel, and Fred doesn't. The result is complete musical chaos ... and then, at 1:07, Fred finds the tune, and they suddenly are both in perfect sync again. Now, this sort of screw-up is almost the worst mistake a competent Irish duo could make. But hell, for me if anything it makes this video stand out in a positive way. Seeing the fumble and recovery is endearing. [1] https://www.youtube.com/watch?v=_0CTHmQ2Jus https://www.youtube.com/watch?v=_0CTHmQ2Jus
