Hi guys back with another thread. From my previous thread called:"How to Memorize at Hearing Intervals" I learned a lot about how the intervals their names and how songs are created using intervals, and determine to if a interval is minor second or major second, minor third in a song. Now that I have accomplished that - the thing now is how do I determine where chords come into play. For instance, if you take the Happy Birthday tune I learned the melody to it but where do chords come in at? And that is what I'm asking how to determine chords from a melody? How to determine a chord in a song even when there is a major second in a melody or is it more to it than just having a major second interval in a song? And does it take more intervals to make a song. Its just what I'm asking.
