Hi, here is a great song to learn...the classic of morricone, duo of bass and flute

I was playing these one with my bass professor (the one who plays it in the video)
What I like most about his interpretation is the way he plays it with chords with a very relaxed feel and the bass solo at 2.08 seconds...
An example of how to play with emotion and relax...
