Hi, folks. Hope you are doing great. I am learning the chord progression. I’m having big trouble with it. Assume I wrote a melody and wrote a chord progression to the melody. It seems to me the purpose of a chord is to provide guidance for accompaniment. Every tutorial I came across says - write C chord for a measure that has C E G. But most measures don’t just have the chord notes. What if it has an F in it and I’m trying to apply my favorite arpeggio pattern I learned to the melody. The E and F will clash. It sounds awful. This is only the semi-tone interval, and there are tritone and two-semi-tone intervals and four-semi-tone intervals and the sharps and flats. Let’s say another violinist or a guitarist is looking at the chord and trying to play along, there is possibility his E will clash with the F too. Out of frustration, I bought Band-In-A-Box, thinking maybe the pros know how to do it. The result is awful, one clashing sound after another. No one talks about this issue. I see those instructors who give tutorials fly through with ease with no clashing sound. There must be a way of doing this.

Thanks a lot for your input.
