So there's this Japanese man watching a jazz band. In the interval he goes up to the guitarist and says "Can you play - jazz chord?"
The guitarist says "Yeah, how about Cmaj9", and plays the chord.
"Velly nice", says the Japanese, "but can you play- jazz chord?"
The guitarist thinks for a moment and says "Ok,how about Bb9+6?", and plays the chord.
The Japanese says "Velly nice, but can you play -jazz chord?"
The guitarist is a bit perplexed by now, so he says "I'm sorry I don't understand what you mean".
'You know', says the Japanese and starts to sing
