many great song arrangers have been bassists. from pop music to heavy metal and rock to jazz, there are myriad examples of bass player/arrangers/producers. seems like the bass position in a band has a unique insight into the functions of all the other instruments in a song, and many capable bassists have capitilzed upon this insight to put together classic "standards" in every genre. what i would like to discuss is the considerations and concerns involved in arranging a song, taken from the bassist's point of view. one of the things that i have noticed is that one can't just "arrange for staff" meaning bass instruments do this, treble clef instruments do that. guitars are going to have different musical strengths and weaknesses than saxophones are going to have. this goes down to the nature of the way the instruments produce their music - the nature of the notes produced. another concern/effect on this is the general structure of a section within an ensemble and how this affects the arrangements - a 4 note guitar chord is going to sound differently and have a different impact then 4 saxes playing the same chord. or 2 saxes and 2 bones. any thoughts?
