I forgot to write... ...we have a notation system which you can learn in classical music schools. We also have a special guitar notation and drum notation system. I think the second notation system was invented by musicians which wanted to play music instead of studying classical music. It's not wrong to do so and I won't treat here anyone. The main point is: "Having fun with playing music!"

Oh, by the way, that reminds me on some notations I've seen in earlier years. The following inscription... A - D - G - D/G ...means playing an "A" chord for a whole bar, the same with "D" and "G" chord (2nd and 3rd bar) and then playing two quarters of a bar the "D" and the second two quarters of this bar the "G" again. So, the inscription you've mentioned above would really confuse musicians who have learned that way...

That's the reason why I choosed the classical notation system. Every musician from any music conservatory will understand it. The notation system you've mentioned in the top of this topic is not unitary. Why else did your guitarist look blank at you?

If this were a general notation system we wouldn't have this little conversation...

I think it's necessary to unitize the notation system inside your band. No matter what system you'll ever use it's only useful as long as it's unitary...

Okay, this was a little bit (1 or 2) more than only my two pence...
