Great information to aid in showing instrument relationships and responsibilities. It seems the primary cautionary interaction between mandolin and guitar is based on strumming and you guys really explained the good and bad. However, it seems like some additional information night be helpful. Fills were touched on but more info on which instrument does the fills when would be helpful. Also, it seems like the relationship between the mandolin and banjo may be more complex. Both instruments can vamp the off beat and both can pick or roll leads, fills, or active backup depending on the band style, with the mandolin doing mostly chops. I guess the question is; isn’t the relationship between the mando and banjo a bit more complex and impactful to the band sound which begs paying attention to who does what backup and fills when?
