If someone inverts the chord then the bass is not the "real" root note of the chord anymore. So if I heard an "A" this might not be an A major (or minor).
So how would I know if the chord is inverted or not, if I listen by ear. Is there a special trick?
One thing I've been doing is listening to the overall tone of the chord. Regardless of inversions, for example a C chord which has:
first inversion: EGC
second inversion: GCE
If I play any of these chords to a tuning app on my phone, they all appear to firmly point to "C". Which to me indicates the overall tone and that's what I listen to. Or I hum a main harmonic tone as I'm listening to the song. And whatever I hum is the chord essentially.
But is that how people normally do it by ear? just figure out main tone? because I heard somewhere that people listen to the bass notes. But I don't get how they can listen to bass notes because as mentioned the chord could've been inverted.
