Hahaha I like the process there.
Well the only thing is to listen to the recordings rather than 'understand it' like some academic ponce (me).
In baby loser talk: Pedal tone = A note that continues for a long time over different chords. Sounds good cuz it becomes familiar, even if it's technically 'wrong'. Ergo, therefore, vis a vis, thus, Any note can sound good anywhere
