I hear more then I used too. I play acoustic guitar, and was always impressed by other guitar players who could figure out the chords of songs just by listening.

It’s like ok that is a D chord…but it sounds different played on a piano, because the piano player colours the chord with more notes making it sound full and rich and subtly different, I’d play the D shape on my guitar, and think, sorta sounds like, but missing something, must be the wrong chord.

But it is the right chord after all, without the additional colour a piano brings.

Just figured out the guitar chords for Kay-Lynn’s
Standing Here, which is her melody, played with Suno piano, I thought, I’ll never figure this out….but I recognized parts of her melody from an old Irish tune I once learned….so I was able to figure out the key. I learned it in the key of D. But my the notes I learned where off….darn all I had to do was drop it down half tone…and it fit! So yeah…must be Db…..tried the Db flat on my guitar, and it worked.
Then tried the 4 and the 5 chords and they worked too. That left just one chord, that to me is the most beautiful chord, just at the end of the verse…so nice, and just had to experiment to find it….


But I never would have been able to do any of that before.
