Currently there is the melody dictation ear trainer. It would be great if there was a separate ear training app focused solely on chord progressions without the melody.
It would work so that you hear a chord progression and then select the chords (e.g. I-IV-V-I) that you heard.
I think this is a great idea and would use it.
totally agree. A full ear training platform is something that is very much on the Hooktheory roadmap. We have a lot of ideas on this front, and chords/harmony will definitely be a part of this.
Chord Prog ear trainer does this really well.
