I've been engrossed in Jazz music for 8 months now. Since I've had 9 years experience on guitar, I can usually pick out and sing the melody being played. However, chord tones and their harmonic 'togetherness' cause my ear to stumble.
To dissect this further, I played simple open chords on my guitar:
An A minor, C major, Cmajor 7. I'd try to sing what I hear and find myself flat. If I arpeggiate the chords, I can sing the tones.
I'm wondering how I can advance my ears ability to hear chord tones? The discrepancy is strongest when I try to sing them. Is it as easy as keeping an eye on it, continued practice? Or is there a more in-depth lesson plan.
I do have a guitar instructor. We're currently working through classical pieces and I don't believe singing/ear training is his specialty.
Thanks so much guys, sorry for the dense question. I tried to format it so it's easier to read.
