OK, so I've recently joined a cover band and for some of the songs I needed to make charts. I just write down the chord progressions, no notation on how many measures these chords are. Now we've added a keyboardist that wants to use my charts, but he is all confused by looking at them, and I don't blame him, they sometimes confuse me. Anyone have any scans of their charts or explanation as how to properly write them? Is there a standard notation, or does everyone do them differently?
