I agree.
The intervals start out so simply...the root, major third, the 5th...baby stuff, then it just takes off!
kind of like the notes are saying
“Up, Up, and Awayyyyyyy”
It SINGS. If music doesn’t “Sing” I have a hard time enjoying it. I am a Bass Player, and my Teacher (Who is a genuine Rock Star, not kidding!) told me that even a BASS LINE should be a singable melody.
John Williams lifted that melody from Richard Strauss’ ‘Death and Transfiguration’.
