rather than try to write, I think it would be better to provide examples.tapper mike wrote: varying degrees of harshness like it's fighting the chord so being dissonant. You don't have to obsess over everything must always sound as pleasing as possible. Infact when you move from something that sounds dissonant to conosant it's a resolution in and of itself. You can't have resolution without conflict.
is I think as good an example of non-chord tones resolving as a feature of the melody as there is. Simple stepwise, such as 2-1, 'resolution' of the poignant dissonance {For the record, 'dissonance' of say D vis a vis C minor means D vis a vis C, and D vis a vis Eb. However you could have a "CmAdd2" and the dissonance is a chord tone.}. I would say to take this kind of thing by ear and make notes about what happens. I learned to take things off records singing the note, the interval and if I have to transcribe things now I'll do it just from singing the intervals, vis a vis the chord or what-have-you.
I didn't have a reliable voice for it either, but it is essential I think.
