Hey, sorry for the late reply. HookTheory most definitely uses Roman Numeral notation. In the link I posted, change the "Key" pulldown to "Rel", and then you can choose each numeral in sequence. Or, for example, to see all the songs HookTheory thinks use ii-IV-I-V, the link would be: https://www.hooktheory.com/trends#node=2.4.1.5&key=rel https://www.hooktheory.com/trends#node=2.4.1.5&key=rel > HookTheory says that Fm Ab Eb Bb in the key of Eb is also like Closing Time - Semisonic. But vjmanzo's site correctly notes that it's shifted over 2 places: Closing Time is I-V-ii-IV instead of ii-IV-I-V. I don't know what you're referring to here, but it sounds like HookTheory was just suggesting similarities. HT's actual entry for the song you're referring to is here, and has the same progression you mentioned. https://www.hooktheory.com/theorytab/view/semisonic/closing-time https://www.hooktheory.com/theorytab/view/semisonic/closing-... How this relates to your link I have no idea, it shows 404 for me.
