In the taunting of children the 7th harmonics is used according to Leonard Bernstein in his Harvard lectures. We sometimes notate this as sol-mi-la-sol-mi but...it is not correct according to Bernstein although it is the best we can come when playing it on a piano. There is no la in this chant according to him. What we have is the 7th harmonics which is a little higher than la he said. In salve regina (simple tone) we have do-mi-sol-la-sol according to sheet music. In this case the 7th harmonic isnt used but the major sixth above do if we listen to chat theory. Some pentatonic melodies would use the 7th harmonic I've heard some say but salve regina (simple tone) is based on hexachords I am being told so from Do-La there is a perfect sixth and not Do-7th harmonics. What do you experts think of this?
