I’m new new to the music theory and I’m learning it with a hookpad. It’s a greate product! Thank you for you work.
Few days ago I was messing with Progression Builder and I found there are no III, II and VI chords there. First, I thought that progresssion builder is working only with major scale. But then I’ve found v chords sitting next to V chord.
Right now it’s extremly confusing for me… Could you please explain why III, II and VI chords are missing in Progression Builder ?
At Hooktheory we focus on writing music functionally, understanding the purpose of chords in a progression (this, ultimately, is why we bother using Roman numerals in the first place). The function of major chords with roots on scale degrees 2, 3, and 6 (normally minor chords, and thus are not natural to the scale) is typically to cadence to other chords. These chords are known as “applied” or “secondary” chords, and tend toward V, vi, and ii respectively. For this reason they are notated as V/V, V/vi, and V/ii, which you should be able to find in the trends chords. In Hookpad, secondary chords can be entered using the “V/x” checkbox.
yeah right now this is true. All songs are transposed into their relative major for the purposes of the progression builder. Minor mode songs will show up as songs that use the vi chord as their home base (this is a concept we cover in our second book).
