Q: Okay so this is about music: Is the whole switching the 3rd and 7th in tritone substitution meaningless since you just play the same chord pattern, but in the key of the tritone of the written chord of the changes?
A: i think what happens is you actually play the same notes (the notes in the tritone, like E and Bb notes) but switch the bass- play F# instead of C. maybe you already knew that, but i couldn't quite figure out what you were asking
