Wonder if someone might be able to explain this to me? My teacher has asked me to "harmonize" C Major by stepping down the scale with my left hand and playing an appropriate triad with my right. Say, C with left hand, C E G with right. I realize that each note has 3 possible combinations and that these are repeated (C E G could work with E and G as well). I guess I'm having trouble with the term 'harmonize'. To me any combination sounds fine but he winced when I played B D F to harmonize with B. Could someone suggest a harmonization to me and tell me why you chose the triads you did? Thanks!
