Have a listen to the great Peter Baartmans . The essence of great arranger playing is being able to interpret the instrument that you are correctly like the instrument in a real world environment would sound . With Peter, whether he's playing the guitar, saxophone, a trumpet, a piano organ, he will always play the instrument in the way that you would naturally hear it sound in a real live environment. Have listened to this clip and tell me if it doesn't move you and why . http://m.youtube.com/watch?v=TRn-HINlfWg&feature=plcp
